Pyrrolidine catalyzes very efficiently, presumably via iminium activation, the formation of acyloximes, acylhydrazones, and thiosemicarbazones derived from aromatic and aliphatic aldehydes using equimolar amounts of reagents and green solvents. Experimental simplicity and excellent yields after a simple filtration are the main advantages of the method, being an alternative to those currently available especially for the acyl derivatives, which do not work under uncatalyzed conditions. Its application to the synthesis of acyloximes by direct condensation between aldehydes and acylhydroxylamines is unprecedented.

Intermolecular carbon radical addition to the carbon-nitrogen double bond of oxime ethers and hydrazones was studied. The reaction of unactivated aldoxime ethers proceeded smoothly in the presence of BF3·OEt2 to give the alkylated products in high yields via the free radical-mediated carbon- carbon bond-forming process.
