Abstract

Sterically overloaded trisilylmethanes R∗(Me3Si)(Me2XSi) CY Me2SiX CYR∗(SiMe3)(X= H, Br, F, OH, OMe, OC6F5, OTf, Me, nBu, Ph; Y= H, Br, Me) with R∗= supersilyl SitBu3 are accessible via Me2SiH CHR∗(SiMe3)(from Me2SiHCl and LiCHR∗(SiMe3)). The latter compound reacts (i) with Br2 to Me2SiBr CHR∗(SiMe3) which is transformed with AgF, H2O, MeOH, C6F5OLi, MeLi, nBuLi, PhLi into Me2SiX CHR∗( ...
