Ruthenium-arene complexes containing phosphines with pendent aryl groups [RuCI2(rl6-p-cymene) -(PCy2(CH2)3Ar)], Ar = C6H5 and 3,5-(CH3)2-C6H 3 (1 and 3), and the resulting chelating complexes [RuC12(PCy2-(CH2)3-'q6-Ar)] (2 and 4) mediate the cyclopropanation of olefins with ethyl diazoacetate. Compa
