Abstract
The enantioselectivity in the first catalytic conversion of styrene to its epoxide by a homochiral ruthenium porphyrin- 1-Ru(O)(2)-displayed a remarkable sensitivity to the solvent and the identity of the oxida nt. The latter phenomenon clearly indicates that several high valent i ntermediates with different selectivities participated in oxygen atom transfer from catalyst to substrate. These observations are anticipate d to significantly affect research of metal complexes of other homochi ral porphyrins as well. Copyright (C) 1996 Elsevier Science Ltd
