Abstract

Rh-catalyzed C C bond formation in neat water under basic conditions has been efficiently performed. The addition of various boronic acids to styrene, 2-vinylpyridine, and cyclic α, β- unsaturated ketones has been realized with high selectivity and yield. We have shown that m-TPPTC (tris (m-carboxyphenyl) phosphane trilithium salt) exhibited a higher reactivity compared to TPPTS. These couplings could also be conducted very efficiently under basic ...
