The hydroformylation of vinyltrimethylsilane catalyzed by transition metal complexes has been studied.Rh catalysts showed high activity with low regioselectivity.Addition of large excess of triphenylphosphine improved the regioselectivity to normal aldehyde.In contrast, a Co and a Pt catalyst gave exclusively n-aldehyde.Vinyltrimethoxysilane is also hydroformylated by transition metal catalysts.The factors of regioselectivity are discussed.
