摘要

Alkyllithium compounds selectively metalate methyldiphenylphosphine, dimethylphenylphosphine, and di-n-hexylmethylphosphine on a methyl carbon atom to give the corresponding phosphino carbanions in yields ranging from 14-54%. The relative rates of metalation of dimethyldodecylphosphine to dimethyldodecylamine have been found to be ca. 15: 1. The enhanced rates of metalation of the methylphosphines provide evidence for ...
