also substituted by various alkoxides to give a series of diastereomerically and enantiomerically pure carbaboranylferrocenyl phosphinites ((RP,RFc/SP,SFc)-7, (RP,RFc/SP,SFc)-8, (RP,RFc/SP,SFc)-9, (SC,RP,RFc)-10, and (SC,RP,RFc)-11). The substitutions occurred with 100% stereoselective inversion of the configurations of the phosphorus centers. The phosphinites display high stability toward oxidation and
