摘要

The synthesis of three triphenylphosphine analogues with phenyl groups replaced by (4-tert- butyl) phenyl and (3-sulfonato) phenyl group is described. The surface-active properties of these new compounds are reported. The catalytic activities obtained with these phosphines in the palladium-catalyzed cleavage of undecyl allyl carbonate were up to 24000 times higher than those observed with trisulfonated triphenylphosphine, the ligand typically ...
