The acylphosphonate function as an activating and masking moiety for the α-chlorination of fatty acids

α-Chloroacylphosphonates were prepared in situ by chlorination of acylphosphonates using sulfuryl chloride and were subsequently cleaved to the corresponding α-chlorinated fatty acids with hydrogen peroxide - sodium bicarbonate.

Halogen atom transfer radical cyclization of N-allyl-N-benzyl-2,2-dihaloamides to 2-pyrrolidinones, promoted by Fe0-FeCl3 or CuCl-TMEDA

The halogen atom transfer radical cyclization of a N-allyl-N-benzyl-2,2-dihaloamides to 2-pyrrolidinones has been carried out in high yields under mild conditions, in a reaction promoted by CuCl-TMEDA or Fe0-FeCl3 in acetonitrile or N,N-dimethylformamide, respectively.
