title: Reactions of (Triphenylsilyl)ethylene Oxide with Grignard Reagents (and with MgBr(2)). A Reinvestigation.
abstract: Reactions of (triphenylsilyl)ethylene oxide (1) with simple Grignard reagents such as EtMgBr and PhMgBr have been reported to yield crystalline hydroxysilanes assigned as the alpha-hydroxy silanes expected from beta opening of the epoxide. Reinvestigation of these reactions showed that the hydroxysilanes were the beta-hydroxy silanes 4 and 7 expected from a rearrangement-trapping sequence; a bromohydrin, assigned as the alpha-bromo-beta-hydroxy silane 9 from alpha opening, and (triphenylsilyl)acetaldehyde (8) were also formed.
