Product 1

HCID 13750329Docosyl(diphenyl)phosphaneYield 96%

Procedure

In a manner similar to Example 1, docosene (obtained from Aldrich) and diphenylphosphine were reacted under nitrogen at 250° C. for 27 hours. Removal of unreacted olefin and diphenylphosphine by vacuum distillation gave docosyldiphenylphosphine. The yield was 96% based on recovered olefin. The conversion was 57% based on recovered olefin.
