Procedure

The known but unavailable 2,2-dimethylpropyl diphenyl phosphine was derived via reacting 2,2-dimethylpropyl chloride with lithium diphenyl phosphide in a refluxing tetrahydrofuran-hexane solvent mixture. After filtering off the lithium chloride by-product, the 2,2-dimethylpropyl, (i.e., neopentyl) diphenyl phosphine was obtained by the fractional distillation of the filtrate between 109° and 110° C. at 0.1 mm.
