Funktionelle Trimethylphosphinderivate, XII Stabilisierte Carbanionen: Phosphinomethanide und ihre Reaktion mit Methyliodid /Functional Derivates of Trimethylphosphine, XII Stabilized Carbanions: Phosphinomethanides and their Reaction with Methyl Iodide

Abstract

Phosphinomethanides {[(CH₃)₂P]_nCH_3-n}Li (n = 1, 2, 3) are obtained from the parent phosphines by reaction with organolithium reagents. The metalation is facilitated with increasing n. With methyl iodide reaction takes place at the phosphorus atom exclusively, yielding stabilized ylids for n = 2, 3.
