Recently we have demonstrated that the ferrio-silanol (RS,SR)-l is available, starting either from the diastereomerically pure ferrio-chlorosilane (i / ,5 -Cp(OC)(Ph3P)Fe-Si(Me)(Cl)(Ph) or the ferrio-silane (R5,Si )-Cp(OC)(Ph3P)Fe-Si(Me)(H)(Ph). In both cases, the transformation to the ferrio-silanol 1 - Cl/OH-exchange at silicon or insertion of oxygen into the Si-FI bond using dimethyldioxirane - occurs stereospecifically [3],... [Pg.408]

Fe S oS si)-ll and (5Fe5c5si)-H represent the first ferrio-silanes with three defined stereocenters, which offer interesting perspectives with respect to reactions involving the (OH)Si- or the (CH2=CH)Si-group. [Pg.410]

As shown in earlier works, the Si-H bonds in ferrio- and ruthenio-silanes Cp(OC)2M-SiR3- H (M = Fe, Ru R = alkyl, aryl n = 1-3) are extremely sensitive towards insertion of oxygen using dimethyldioxirane. This route has been utilized to generate diverse ferrio- and ruthenio-silanols, e.g., Cp(0C)2M-SiR20H (M = Fe, R = fflu M = Ru R = oTol) [6],... [Pg.269]
