Spectroscopic and electrochemical investigation of coordination complexes of octakis(benzylthio)tetraazaporphyrincobalt(II)

Synthesis of new bichromophoric di- and pentanuclear complexes 2-7 by datively binding (bpy)2RuII, (phen)2Ru II and Cp (PPh3)RuII units to the periphery of [Co(OBTTAP)], 1, and their spectroscopic properties are described. IR, 1H NMR, UV-Vis, and mass spectral data were used for their characterization. Relative intensities and positions of the Soret and Q-bands absorptions in the di- and pentanuclear complexes were observed shifted vis-a-vis that in the precursor complex [Co(OBTTAP)], 1. These complexes particularly, those possessing [Co(OBTTAP)] and (bpy)2Ru II/(phen)2RuII units, exhibited efficient inter-component electronic excitation energy transfer in their fluorescence excitation-emission spectra, that are suggestive of a high degree of inter-component electronic interaction in them. Also, the electrode activity of the complexes improved upon binding of the peripheral units and they exhibited multiple one-electron reversible oxidation waves in the cyclic voltammograms. These effects have been explained in terms of dpi(S)-dpi(Ru) interactions.

A straightforward access to ruthenium-coordinated fluorophosphines from phosphorous oxyacids

The transformation of phosphorous oxyacids into the corresponding fluorophosphines was mediated by [RuCp(PPh3)2Cl] under mild reaction conditions using a soft deoxofluorinating agent. The reaction is selective, proceeds with high yields and can be extended to a wide range of phosphorous oxyacids once coordinated to the ruthenium synthon [RuCp(PPh3)2]+ as their hydroxyphosphine tautomer. Deoxofluorination of phenylphosphinic acid was also mediated by [RuCpR(CH3CN)3]PF6, where CpR: Cp = C5H5, Cp? = C5Me5, and [Ru(eta6-p-cymene)(mu-Cl)Cl]2. X-Ray single crystal structures of the two new derivatives, [RuCp(PPh3)2{PhP(OH)2}]CF3SO3 and [Ru(eta6-p-cymene)Cl2{PhP(OH)2}] have been determined.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8

PROCESS FOR CO-PRODUCING OLEFINS AND DIESTERS OR DIACIDS STARTING FROM UNSATURATED FATS

In order to produce both an olefinic fraction and a composition of diacids or diesters of fats, a process is carried out which comprises, in succession: a) metathesis of an unsaturated fat with ethylene in the presence of at least one non-aqueous ionic liquid; b) separating and recycling the ionic liquid used in the first step; c) separating, by distillation, the olefinic fraction (fraction A) from the unsaturated fat mono-ester or mono-basic acid fraction (fraction B) formed in step a); d) homometathesis of the mono-unsaturated fat ester or acid cut (fraction B) which allows the co-production of unsaturated fat diesters or diacids (fraction C) and ethylene which is recycled to the first methathesis step of the process; and e) optionally, recycling the ionic liquid containing the catalyst used in step d). Of particular application to an oleic sunflower oil, an oleic rapeseed oil or to a mixture of mono-alcohol esters of said oils, whereupon the process can produce both an olefinic fraction (mainly composed of 1-decene) and a composition of diesters or diacids wherein, in general, over half of the chains is constituted by unsaturated C18 chains (mainly composed of octadecene-9 1,18-diacid or diester) and to recycle the ethylene employed.

Application of olefin metathesis in the synthesis of steroids

Over the past decade, ruthenium-mediated metathesis transformations, including cross-metathesis, ring-closing metathesis, enyne metathesis, ring-opening metathesis polymerization, and also tandem processes, belong to the most intensively studied reactions. Many applications of olefin metathesis in the synthesis of natural products have been recently described. Also in the field of steroid chemistry new methods of total synthesis and hemisynthesis based on metathesis reactions have been elaborated. Various biologically active compounds, e.g. vitamin D and hormone analogues, steroid dimers and macrocycles, etc. have been prepared using a variety of olefin-metathesis protocols.

An efficient, modular approach for the synthesis of (+)-strictifolione and a related natural product

An efficient, library amenable, “pot economical” total synthesis of (+)-strictifolione and the related natural product, (6R)-6[(E,4R,6R)-4,6- dihydroxy-10-phenyl-1-decenyl]-5,6-dihydro-2H-2-pyrone, are reported. This modular approach takes advantage of two consecutive phosphate tether-mediated, one-pot, sequential protocols, followed by a final cross metathesis to deliver both antifungal natural products in a three-pot process from the respective enantiomeric (R,R)- and (S,S)-trienes with minimal purification. A salient feature of this route is that additional protecting groups are not required as a result of the orthogonal protecting- and leaving-group properties innate to phosphate triesters.
