Le (chlorodiisopropyl)silyl fluorenyllithium: Un equivalent synthetique du diisopropyl(fluorenylidène)silene
摘要:
The metalation of chlorodiisopropylfluorenylsilane 1 with n-butyllithium leads to the alpha-silyllithio compound 3. Compound 3 has a surprising stability and does not afford the diisopropyl(fluorenylidene)silene but behaves as its synthetic equivalent; i.e. it is a useful reagent for "Wittig-Peterson" reactions with various carbonyl compounds leading readily to diisopropylsilanone and fluorenylidene derivatives.
