Zirconium fluoride was utilized to promote efficiently iron-catalyzed aminocarbonylation between alkynes and amines without the use of extra ligands. In particular, this new system is applicable to a wide range of amine and alkyne substrates affording α,β-unsaturated amides in good to excellent yields. Preliminary mechanistic studies reveal the activation model involving interactions of ZF4 with both iron catalyst and amine substrates.

Chemical and electrochemical reductions of N-aroylaziridines 1 are described and compared.The first step is a single electron transfer (1 +e -> 1-. -> 1'-.).But compounds obtained from 1'-. are depending on the method used way followed: chemical reduction of N-cinnamoylaziridine 1e provides pyrrolidone 10e; but oxazoline 11e is available by electrochemical reduction of the same starting material 1e.Counter ion seems responsible of these different results.In agreement with this hypothesis, it is shown that pyrrolidone 10e is obtained from 1j only in presence of a counter ion.
