An iron catalyst is shown for the first time to promote transfer hydrosilylation with silyl formates and is utilized for the silylation of alcohols. Attractive features of this protocol include the use of an earth-abundant transition-metal catalyst, mild reaction conditions, and the release of gases as the only byproducts (H 2 and CO 2).
Siloxane bond formation by heterofunctional condensation of alkoxysilane and halogenosilane. Application to the preparation of copoly(tetramethyl-p-silphenylenesiloxane-dimethylsiloxane)

Siloxane linkages are formed non-hydrolytically by the reaction of dihalogenosilanes with either dibenzylether, or dibenzyloxysilanes and dibenzhydryloxysilanes.The heterocondensation reaction is activated in the presence of NaI (in acetonitrile) or fluoride anions.This offers an alternative copolymerization route to the usual dehydrocondensation of SiOH-terminated species.Thus, the title copolymer was prepared by reaction of equimolar amounts of Me2Si(OCHPh2)2 and 1,4-bis(chlorodimethylsilyl)benzene at 100 deg C.The 29Si NMR spectrum supports a quasi-random sequence in the copolymer.Thermal stability is similar to that reported for an alternating microstructure, as inferred from thermogravimetric analysis.

O-SILYLATED KETENE ACETAL CHEMISTRY; DIVINYLOXYSILANE DERIVATIVES AS NOVEL AND USEFUL BIFUNCTIONAL PROTECTING AGENTS FOR H-ACIDIC MATERIALS

Novel reagents, bis(1-methoxy-2-methyl-1-propenyloxy)silanes (2a-d) have been shown to be very useful bifunctional protecting agents for various types of H-acidic materials, such as diols, dithiols, diacids and their combined materials.The reaction proceeds rapidly under mild conditions to give the corresponding silylene derivatives in almost quantitative yields.
