Heating of pentacarbonyliron with tris(trimethylsilyl)silane results in lib
eration of hydrogen and formation of hexakis(trimethylsilyl)disilane. Photo
initiated reaction of the same compounds begins with oxidative addition of
the silicon hydride to the iron complex with liberation of carbon(II) oxide
. Subsequent transformations of the adduct lead to formation of bis(trimeth
ylsilyl)silanediyitricarbonylhybrido(trimethylsilyl)iron which can be stabi
lized as an adduct with hexamethylphosphoramide.
