Cyclopropylidene Dianion Equivalent. Preparation of 1,1-Dilithio-2,2-diphenylcyclopropane
Oku, Akira,Ose, Yasuyoshi,Kamada, Tohru,Yoshida, Tomohiro
, p. 573 - 576 (1993)
The title compound was prepared by the treatment of corresponding 1,1-dibromocyclopropane with lithium naphthalene radical anion (Li-C10H8).Trapping of the dilithio compound by chlorotrimethylsilane provided evidence for its highly basic profile which can compete with silylation.
Nucleophilic Addition of Lithiated Phenyl Trimethylsilyl Sulfide to Activated Olefins. A Facile Synthesis of 2-(Functionally) Substituted Silylcyclopropanes
Schaumann, Ernst,Friese, Carsten,Spanka, Carsten
, p. 1035 - 1037 (2007/10/02)
The lithio derivative of phenyl trimethylsilylmethyl sulfide undergoes smooth addition to activated ethylene derivatives to afford trimethylsilylcyclopropanes, except for the addition to methyl 2-phenylpropenoate which leads to the formation of methyl 4-trimethylsilyl-2-phenyl-4-(phenylthio)butanoate.
