(R,R)-(ON+)(Salen)ruthenium(II) complex 2 was found to be an effective catalyst for cis-selective asymmetric cyclopropanation (up to 89% ee) which was performed under sunlight coming through a window or incandescent light. Furthermore, (R,R)-(ON+)(hydroxo)-(salen)ruthenium(II) complex 5 was also found to show good cis- and enantio-selectivities (up to 92% ee) in the reaction in the dark.
