Intermolecular carbon radical addition to the carbon-nitrogen double bond of oximeethers 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.

thiosemicarbazones derived from aromatic and aliphaticaldehydes 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
