method for the phosphonyl C2,C3C bond formation under the freeradical, reductive conditions is described. The new approach is based on the synthesis of novel2- and 3- phosphonyl radicals 6, 9 derived from the corresponding 2- and 3-halo (XCl, Br, I) substituted phosphonates 7, 10 and their reaction with alkenes 4. Functionalizedphosphonates 5, 8 possessing the 2+2 and 3+2 elongated carbon chain were
