alpha-Mono- and alpha, alpha-disubstituted alpha-phosphoryl radicals 9 were generated from the easy accessible alpha-phosphoryl sulfides 4, 5 and alpha-phosphoryl selenides 11, 12 and reacted with the electron rich alkenes 6 under the reductive (n-Bu(3)SnH/AIBN) conditions to give the functionalized phosphonates 7 in 32 divided by 68% yield. Two fragmentation processes of the phosphonate a-alkoxy alkyl radicals are also described.
