Synthesis of Aryl Phosphines via Phosphination with Triphenylphosphine by
Palladium Catalysts. — Aryldiphenylphosphines are synthesized by
05- 161 Supported
phosphination of functionalized aryl bromides, triflates and chlorides with triphenylphosphine catalyzed by supported palladium catalysts. Hindered substrates give
lower yield in the reaction on alumina even the bromide analogue of (IV) shows no
phosphination reaction after 14 days. For aryl chlorides, addition of NaI improves the
rate of reaction and yields for reactions on charcoal. — (WANG, Y.; LAI, C. W.;
