Decomposition of the intermediate resulting from the reaction of Fe(CO)2(NO)(η³-propenyl) (1) with a nucleophile -CH(CO2Et) (A) (2_i A=CO2Et, i=1; A=CN, i=2) has been carried out under a variety of conditions using in particular two nucleophiles added, respectively, before and after the formation of the intermediate.The composition of the mixture of alkylation products obtained suggests that reaction of 1 with 2_i is reversibly by complexation of the nucleophile with a concomitant η³ to η¹ conversion of the allyl ligand.
