A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu.

Whereas the boomerang ligand of Hoveyda-Grubbs pre-catalysts can be modified by attachment of a pyridinium tag to its benzylidene moiety, a precise adjustment of the length of the spacer allows the optimum balance to be reached between the activity of the catalyst and its recoverability, exceeding 98% after 6 catalytic runs in the best case.

Related Products of 246047-72-3, An article , which mentions 246047-72-3, molecular formula is C46H65Cl2N2PRu. The compound – (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium played an important role in people’s production and life.

The first total synthesis of the marine dolabellane diterpene (+)-4,5-deoxyneodolabelline (1) has been accomplished. The highly efficient approach is characterized by the convergent assembly of dihydropyrans 2ab and cyclopentylsilanes 3ab. Allylic silane 3a was prepared from 2- methyl-2-cyclopentenone via a copper-catalyzed 1,4-addition followed by diastereoselective alkylation of the resulting enolate. A chemical resolution of racemic cyclopentanone 8 was effected by (S)-CBS-catalyzed borohydride reduction. Direct hydroxymethylation of the enantioenriched ketone 8 to form allylic alcohol 14 was achieved by a Stille palladium-catalyzed cross-coupling from the cyclopentenyl triflate 13. Treatment of the corresponding allylic phosphate 15 with trimethylsilylcopper reagent provided for displacement with allylic transposition yielding the exocyclic allylsilane 3a with excellent diastereoselectivity. Dihydropyrans 2a and 2b were prepared from optically pure acyclic acetals via ring-closing metathesis. Coupling of 3a and 2a or 2b via the carbon-Ferrier protocol gave trans-2,6-disubstituted dihydropyrans 30 and 35 with complete stereoselectivity. Vanadium-based pinacol coupling reactions were explored for closure of the mediumsized carbocycle to yield syn-diol 33. X-ray diffraction studies of the monobenzoate 34 have provided unambiguous stereochemical assignments. Substantial ring strain accounted for the lack of alkene products typical of reductive elimination using TiCl3 and zinc-copper couple (McMurry) conditions leading to 37. Finally, the natural product 1 was obtained via Swern oxidation of the diol 37.

Synthetic Route of 246047-72-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a patent, introducing its new discovery.

The first ansa-nickelocenes, [Ni(eta5,eta5-C 5H4-CH2-CH=CH-CH2-C 5H4)] (4) and [Ni(eta5,eta5- C5H4(CH2)2-CH=CH-(CH 2)2-C5H4)] (5), and a bridged binickelocene, [Ni2(eta5,eta5-C 5H4-(CH2)2-CH=CH(CH 2)2-CsH4)2] (6), were prepared by alkene metathesis of 1,1?-disubstituted nickelocenes. Compound 4 reacts with hydrogen to yield ansa-nickelocene 7, bearing the saturated bridge. The new compounds were characterized by UV-vis, IR, MS, 1H NMR, magnetic susceptibility, and electrochemical measurements. Crystal and molecular structures of 4, 6, and 7 were determined by single-crystal X-ray analysis. These measurements show that the studied ansa-nickelocenes exhibit properties similar to those of nickelocene.

An efficient 1,4-hydrovinylative cyclization reaction of triynes and tetraynes catalyzed by ruthenium alkylidene complexes under ethylene is described. The regioselectivity of vinyl group incorporation can be controlled by the nature of the substituent on the alkyne, and the Grubbs second-generation catalyst is the most effective among typical ruthenium alkylidene complexes.

Alkene metatheses in transition metal coordination spheres: Dimacrocyclizations that join trans positions of square-planar platinum complexes to give topologically novel diphosphine ligands

The alkene-containing phosphines PPh((CH2)nCH=CH 2)2)2 (4) are prepared from PPhH2, n-BuLi, and the corresponding bromoalkenes (1: 2 : 2), and combined with the platinum tetrahydrothiophene complex [Pt(mu-Cl)(C6F 5)(S(CH2CH2-)2)]2 (12) to give the square-planar adducts trans-(Cl)(C6F5) Pt(PPh((CH2)nCH=CH2)2)2 (11, 93-73%; n = a, 2; b, 3; c, 4; d, 5; e, 6; f, 8). Ring-closing metatheses with Grubbs’ catalyst (2) are studied. With 11e, two isomers of trans-(Cl)(C6F5)Pt(PPh(CH2) 14P(CH2)14Ph) (15e) are isolated after hydrogenation. Both form via dimacrocyclization between the trans-phosphine ligands, but differ in the dispositions of the PPh rings (syn, 31%; anti, 7%). The alternative intraligand metathesis product trans-(Cl)(C6F 5)Pt(PPh(CH2)14)2 (16e) is independently prepared by (i) protecting 4e as a borane adduct, H 3B¡¤PPh((CH2)6CH=CH2) 2, (ii) cyclization with 2 and hydrogenation to give H 3B¡¤PPh(CH2)14, (iii) deprotection and reaction with 12. The sample derived from lie contains ?2% 16e; mass spectra suggest that the other products are dimers or oligomers. The structures of syn-15e, anti-15e and 16e are verified crystallographically, and the macrocycle conformations analyzed. As expected from the (CH2)n segment length, 11a undergoes intraligand metathesis to give (Z,Z)-trans-(Cl)(C6F5)Pt(PPh(CH2) 2CH=CH(CH2)2)2 (86%), as confirmed by a crystal structure of the hydrogenation product. Although lib does not yield tractable products, 11c gives syn-(E,E)-trans-(Cl)(C6F 5)Pt(PPh(CH2)4CH=CH(CH2) 4P(CH2)4CH=CH(CH2)4Ph) (21%). This structure, and that of the hydrogenation product (syn-15c; 95%), are verified crystallographically. Analogous sequences with 11d,f give syn-15d,f (5 and 14% overall).

A flexible and unified strategy for syntheses of cladospolides A, B, C, and iso-cladospolide B

A simple, efficient and flexible strategy for the syntheses of cladospolides A-C and iso-cladospolide B is reported here. This strategy involves Julia-Kocienski olefination and Yamaguchi macrolactonization as key steps, starting from either d-ribose or suitable tartaric acid esters. Although our initial efforts towards cladospolide A involving a ring closing metathetic approach were not successful, changing the mode of ring closure and the use of Julia-Kocienski olefination for the construction of the key intermediate solved this issue and paved the way for the completion of total syntheses of this class of natural products.

Evaluating transition-metal-catalyzed transformations for the synthesis of laulimalide

(Chemical Equation Presented) Laulimalide is a structurally unique 20-membered marine macrolide displaying microtubule stabilizing activity similar to that of paclitaxel and the epothilones. The use of atom-economical transformations such as a Rh-catalyzed cycloisomerization to form the endocyclic dihydropyran, a dinuclear Zn-catalyzed asymmetric glycolate aldol reaction to prepare the syn 1,2-diol, and an intramolecular Ru-catalyzed alkene-alkyne coupling to build the macrocycle enabled us to synthesize laulimalide via an efficient and convergent pathway. The designed synthetic route also allowed us to prepare an analogue of the natural product that possesses significant cytotoxic activity.
