WebDec 16, 1999 · Catalytic asymmetric allylation of aldehydes with allylic trimethoxysilanes was achieved with the p-Tol-BINAP⋅AgF complex as catalyst [Eq.(a); p-Tol-BINAP=2,2′-bis(di-p-tolylphosphanyl)-1,1′-binaphthyl)].High anti and enantioselectivities were obtained in the reaction with crotyltrimethoxysilane, irrespective of the configuration at the double bond. WebMar 9, 2002 · Abstract Water has a big influence on the mechanism of monolayer formation and therefore on the structure of monolayer that can be obtained on a silica surface. Trimethoxysilane in the absence of water can form submonolayers with only one siloxane bond binding functional tails with the surface.
