Suzuki cross-coupling reactions catalyzed by palladium complex of an inexpensive phosphinite, 2-diphenylphosphinoxynaphthyl
نویسندگان
چکیده
A facile and less expensive monophosphinite ligand 2-(diphenylphosphinoxy)-naphthyl, C H OPPh (1) has been synthesized from the reaction 10 7 2 f -naphthol with chlorodiphenylphosphine. The mixture of Pd(OAc)2 and 1 catalyzes the Suzuki cross-coupling of a variety of aryl halides with ryl boronic acids at room temperature or at 60 ◦C, giving generally high yields even under low catalytic loads. The effect of solvent, base and atalyst loading on the coupling reaction of aryl halide with arylboronic acid is also described.
