Reactions d'alkylation de Fe(CO)2(NO) (η3-propenyl) par des nucleophiles carbones. Nature de l'intermediaire reactionnel
Decomposition of the intermediate resulting from the reaction of Fe(CO)2(NO)(η3-propenyl) (1) with a nucleophile -CH(CO2Et) (A) (2i 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 2i is reversibly by complexation of the nucleophile with a concomitant η3 to η1 conversion of the allyl ligand.
