Tris(trimethylsilyl)methane readily undergoes metallation when treated with methyllithium in a mixture of tetrahydrofuran and diethyl ether, and the [tris(trimethylsilyl)methyllithium produced is remarkably stable in tetrahydrofuran. The ease of formation and the stability of the organolithium compound may be associated with stabilization of the carbanion (Me3Si)3C− by delocalization of the lone pair
