    • We changed the substrate from 6-acetamido-2,2-dimethyl-7-nitrochromene to dihydronaphthalene which provides the more Lewis acid-sensitive epoxide, to clarify the effect of the Lewis acidity of Ru-complexes to the reaction.

    • It has been reported that flash photolysis of Ru(TPP)(NO)Cl presumably generates a transient species, Ru(TPP)Cl: Lorkovic, I. M.; Miranda, K. M.; Lee, B.; Bernhard, S.; Schoonover, J. R.; Ford, P. C. J. Am. Chem. Soc. 1998, 120, 11674-11683. However, we can not remove the possibility that the chloro ligand in 1 dissociates under the present reaction conditions from the result obtained in the asymmetric cyclopropanation described in the succeeding communication.

    • 3). The broad signal at 535 nm became gradually weak with the exposure of complex 1 under the reaction conditions to incandescent light. This probably suggests that the decomposition of complex 1 was brought about on irradiation.
