Reactions between HC?CC?CSiMe3 and several ruthenium halide precursors have given the complexes Ru(C?CC?CSiMe 3)(L2) Cp? [Cp? = Cp, L = CO (1), PPh 3 (2); Cp? = Cp*, L2 = dppe (3)].

Replacement of H in 5 or 6 with Au(PR3) groups was achieved in reactions with AuCl(PR3) in the presence of KN(SiMe3) 2 to give Ru(C?CC?CAu(PR3)}(L 2)Cp? [Cp? = Cp, L = PPh3, R = Ph (7); Cp? = Cp*, L2 = dppe, R = Ph (8), tol (9)].

Application of 32993-05-8, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 32993-05-8, C41H35ClP2Ru. A document type is Article, introducing its new discovery.

A series of RuCp[OC6H3(CH2CH=CH 2-2)(R)](PPh3)n complexes (n = 2, R = H (1a); n = 1, R = 4-OMe (2b), 4-Me (2c), 4-Ph (2d), 4-Br (2e), 4-NO2 (2f), 6-OMe (2g), 6-Me (2h), 6-Ph (2i)) have been prepared in 27-76% yields. These 2-allylaryloxo complexes 1a and 2b-f are in equilibrium between RuCp[OC6H 3(CH2CH=CH2-2)(R)-kappa1O] (PPh3)2 (1) and RuCp[OC6H3(CH 2CH=CH2-2)(R)-kappa1O,nu2C, C?](PPh3) (2) in solution, and 2g-i do not react with PPh 3. The equilibrium constant K1 (K1 = [2][PPh3]/[1]) is about the same for 1a and 2b-f (K1 = 0.07-0.31 M). In contrast to the conventional aryloxo complexes of the late transition metals, treatment of 1a and 2a-g with weak Bronsted acids (HOR) gives a rapid equilibrium with 2HOR. The association constant K2 (K 2 = [2HOR]/([2][HOR])) increases on decreasing the pKa value of the acid employed and on increasing the induction effect of substituents at the 4-position in the aryloxo group. These features suggest present association being regarded as a simple acid-base interaction. Interestingly, further association of 2HOR with the second acid leads to the cleavage of the benzylic C-H bond, giving RuCp[C3H 4{1-C6H3(OH-2)(R)}-nu3C,C?, C?](PPh3) (3). The thermodynamic and kinetic studies suggest formation of hydrogen bonds among two Bronsted acid molecules, lone-pair electrons in the aryloxo oxygen, and a benzylic methylene proton. Such association makes the Ru(II) center more electrophilic to attack the benzylic carbon to give 3.

A series of heterobimetallic complexes consisting of group IV metallocenyl diphosphines and Ru were synthesized and structurally characterized. Most of them work as catalysts toward propargylic substitution reaction of 1,1-diphenyl-2-propyn-1-ol (4) with EtOH. The stoichiometric reactions of the heterobimetallic complexes [MCl2(mu-eta5: eta1-C5H4PEt2) 2RuClCp*] (M = Zr, Hf) with 4 and NaBArF4 afforded key reactive intermediate allenylidene complexes [MCl2(mu- eta5:eta1-C5H4PEt 2)2RuCp*(=C=C=CPh2)]BArF 4, whose molecular structures were confirmed by X-ray analyses. A plausible reaction pathway for the catalytic reaction is proposed where group IV metal chloride and Ru moieties work cooperatively.

Two metals are better than one: The cationic methanethiolate-bridged diruthenium complex 1 (Cp* = C5Me5, OTf = CF3SO3) promotes the catalytic propargylation of aromatic compounds with propargylic alcohols bearing not only terminal alkyne but also internal alkyne units, reactions that can not be carried out with some mononuclear catalysts. This reaction provides a general and environmentally friendly (atom economical, only H2O as byproduct) method for the synthesis of a variety of propargylated aromatic compounds.
