Both MH(Ph)(CO)L2 (L = PtBu2Me; M = Ru and Os) react with vinyl fluoride to form M–F bonds; however, Ru eliminates benzene, while Os eliminates ethylene. In contrast, Ru(H)2(CO)L2 and Os(H)2(CO)(1-butene)L2 both react with vinyl fluoride to give et

The reactions of OsH(Ph)(CO)L 2 (L = P t Bu 2 Me) with HSiMe 3 , H 2 SiPh 2 or H 3 SiPh produce benzene and OsH 3 (silyl)(CO)L 2 , which is characterized as a fac -H 3 OsP 3 shape capped on the H 3 face by the silyl group. For H 2 SiPh 2 and H 3 SiPh

Pincer complexes of the type ((R)PCP)IrH(2), where ((R)PCP)Ir is [eta(3)-2,6-(R(2)PCH(2))(2)C(6)H(3)]Ir, are the most effective catalysts reported to date for the "acceptorless" dehydrogenation of alkanes to yield alkenes and free H(2). We calculate

OsH(Ph)(CO)L2 (L = PtBu2Me, Ph = C6H5) is synthesized and studied by spectroscopic and DFT (B3LYP) calculations. It forms 1:1 adducts with CO or MeCN, but D2 causes reductive elimination of C6H6. Reaction with C6D6 gives exclusively OsD(C6D5)(CO)L2.

Reaction of anhydrous FeCl3 with PtBu2Me in alcohol gives [HPtBu2Me][FeCl3(PtBu2Me)], a salt with a tetrahedral Fe(II) anion hydrogen bonded (via Cl) to the P–H proton of the cation. Reaction of FeCl2(CO)4 with PtBu2Me in benzene, followed by worku

A synthesis of the title compound by hydrolysis of OsH(C6H5)(CO)(PtBu2Me)2 has the advantage that the product shows 1H NMR spectra free of the influence of hydrogen bonding to water impurity. In the solid state, the hydroxyl group interacts weakly wi

OsHCl(CO)L2 (L=PBu2tMe) is transformed to OsCl(NO)(CO)L2 by p-MeC6H4SO2N(NO)Me. Chloride removal with NaBAr4′ [Ar′=3,5-(CF3)2C6H3] yields the nonplanar, unsaturated Os(0) compound [Os(NO)(CO)L2]BAr4′, which is shown to be more reactive towards

The mechanism of (PCP)Ir-catalyzed transferdehydrogenation and a full free-energy profile have been elucidated for the substrate/acceptor couple COA/TBE (COA = cyclooctane; TBE = t-butylethylene). Stoichiometric components of the catalytic cycle have
