Disclosed is a mild, scalable, and chemoselective catalytic cross-dehydrogenative C-H bond functionalization protocol for the construction of C(sp)-Si bonds in a single step. The scope of the alkyne and hydrosilane partners is substantial, providing an entry point into various organosilane building blocks and additionally enabling the discovery of a number of novel synthetic strategies. Remarkably, the optimal catalysts are NaOH and KOH.

Allenic zinc reagents (R1R2C=C=C(R3)ZnL) are efficiently prepared by the reaction of propargylic substrates (R1R2C(X)C≡CH, X = MeSO2O,Cl, R2NCO2) with a variety of tri
Dehydrogenative silation, isomerization and the control of syn- vs. anti-addition in the hydrosilation of alkynes
Jun, Chul-Ho,Crabtree, Robert H.
, p. 177 - 187 (2007/10/02)
Alkyne hydrosilation has been examined in detail for the catalysts SbF6 (L = PPh3, bq = 7,8-benzoquinolinato) and RhCl(PPh3)3.Factors that favor the normal syn- or the unusual anti-silane addition to the alkynes are examined.Two other unus
