Abstract

A novel organoruthenium(iii) amidinate, (η⁵-C₅Me₅)RuCl(η-ⁱPrN=C(Me)NⁱPr) (2), has been prepared by oxidation of organoruthenium amidinate, (η⁵-C₅Me₅)Ru(η-ⁱPrN=C(Me)NⁱPr) (1), by organic chlorides; both 1 and 2 are found to be good catalysts for atom-transfer cyclization of N-allyltrichloroacetamides which are useful for successful preparation of a pyrrolizidine alkaloid skeleton under mild conditions.
