摘要

A mixture of Pd 2 (dba) 3 /{η-C 5 H 4 CH N[CH(CH 3 )(Nap)]}Fe[η-C 5 H 4 P( t Bu) 2 ] efficiently catalyzes the Suzuki reactions of a variety of bulky aryl halides and aryl- and alkyl-boronic acids, affording the desired cross-coupling biaryl products in quantitative isolated yields under mild conditions and at low (1 × 10 −6 –1 mol%) Pd loadings. Spectroscopic (NMR & ESI) analysis of the mixture of Pd 2 (dba) 3 , the hybrid [P,N] ligands, and aryl halides revealed different ...
