A Molecular/Heterogeneous Nickel Catalyst for Suzuki-Miyaura Coupling

A molecular/heterogeneous catalyst motif based on an earth abundant nickel catalyst and SiO2 support has been designed and synthesized. Characterization and catalytic testing indicate that the molecular nickel catalyst [(2,2′:6′,2′′-terpyridine-4′-benzoic acid)Ni(II)]Cl2 attached to a high surface area SiO2 support is the active cross-coupling catalyst and increased product yields are a result of increased molecular stability of the catalyst while attached to the SiO2 support. This molecular/heterogeneous motif is easily separated from reaction mixtures and can be recycled for multiple catalytic reactions. The catalyst is active for Suzuki-Miyaura catalysis at catalyst loadings as low as 0.1 mol %, and turnover numbers nearing 2000 have been achieved.

, p. 771 - 773 (2007/10/03)
The palladium-catalyzed cross-coupling of organolead compounds with organoboranes was carried out in the presence of Pd2(dba)3-CHCl3 (5 mol %), CuI (10 mol %), and NaOMe (6 equiv) in CH3CNXDME (1 : 1) under mild conditions.
