Abstract

The complex [MoCl(η3-C3H5)(CO)2(phen)] was prepared in a one-pot manner from Mo(CO)6, allyl chloride, and 1,10-phenanthroline (phen). This complex reacted with AgOTf to afford [Mo(OTf)(η3-C3H5)(CO)2(phen)] (1). The reaction of 1 with NaBAr‘4 (Ar‘ = 3,5-bis(trifluoromethyl)phenyl) in CH2Cl2 yielded a solution that catalyzed (1% load of the catalyst) the reaction of ethyl diazoacetate with N-benzylideneaniline to give a mixture of cis-(carboxyethyl)-1,3-diphenylaziridine and two enamines. Replacement of phen by chiral ligands based on trans-1,2-diaminocyclohexane failed to induce asymmetry on the obtained aziridine.
