Scope and selectivity of B(C6F5)3-catalyzed reactions of the disilane (Ph2SiH)2

The diverse catalytic activity of the electrophilic borane B(C6F5)3 in reactions of silanes with organic substrates has been exploited extensively in studies that mostly focus on very particular, useful functional group transformations in organic synthesis. This study examines the potential for harnessing the collective, broad scope of these transformations in the preparation of new oligosilane derivatives. Borane-catalyzed hydrosilation, heterodehydrogenative coupling, and dealkylative coupling reactions of a wide range of substrates with the disilane (Ph2SiH)2 were investigated. These allowed new mono- and disubstituted disilanes to be prepared that contain Si-O, Si-S, and Si-C linkages. Challenges and opportunities are described that arise from competing "over-reduction" chemistry, and the sensitivity of the catalysis to both the Lewis basicity and steric bulk of the substrates is examined.

Well-defined NHC-rhodium hydroxide complexes as alkene hydrosilylation and dehydrogenative silylation catalysts

Alkene hydrosilylation and dehydrogenative silylation reactions, mediated by [Rh(cod)(NHC)(OH)] complexes (cod = 1,5-cyclooctadiene; NHC = N-heterocyclic carbene) are described. The study details a comparison of the catalytic activity and steric characteristics of four rhodium complexes bearing different NHC ligands. The novel [Rh(cod)(Ii-PrMe)(OH)] complex (Ii-PrMe = 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidine) was designed to improve the reactivity of Rh(i)-hydroxides and proved to be a successful promoter of hydrosilylation and dehydrogenative silylation, displaying good stereo- and regiocontrol.

Platina-β-diketones as catalysts for hydrosilylation and their reactivity towards hydrosilanes

The platina-β-diketones [Pt2{(COMe)2H}2(μ-Cl)2] (1), [PPh4][Pt{(COMe)2H}Cl2] (2) and [Pt{(COMe)2H}-(acac)] (3) were found to catalyze the hydrosilylation of alkynes (h

Catalytic activity of bis(dialkylamino)carbenium salts in hydrosilylation reactions

Bis(dialkylamino)carbenium salts {[(Me2N)2CCl]+}2MCl4 2- (M = Ni, Pd) and {[Me2NC(X)NR2]+}2PtCl62- (R = Me, All; X = H, Cl, Me) are efficient catalysts for hydrosilylation of allyl phenyl ether, triallylamine, allyl chloride, allylamine, and 1-octene with various hydrosilanes. The catalytic activity is dependent on the salt composition and the nature of the metal M, the saturated compound, and the hydrosilane used. The catalysts used are usually insoluble in the reaction mixture, active, and stable. In some cases, carbenium salts are more selective than Speier's catalyst. Novel catalysts, silica-immobilized dialkylaminocarbenium salts, have been prepared. The kinetics of the reaction have been considered.
