摘要

Abstract (Nitrosyl)(salen) ruthenium (II) complex 1 was found to serve as an efficient catalyst for the epoxidation of conjugated olefins under photoirradiation, with 2, 6-dichloropyridine N- oxide (2) or tetramethylpyrazine N, N′-dioxide as a stoichiometric oxidant. High enantioselectivity was achieved irrespective of the substitution pattern of olefins. The choice of solvent depends on stability of the resulting epoxides: high enantioselectivity is ...
