The generation of vinyl or aryl radicals under classical, thermal AIBN/n-Bu3SnH conditions at 80 degreesC in the presence of an excess of (MeO)(3)P gives rise to the corresponding vinyl- or arylphosphonates in good yields. This approach complements the photochemical reactions of the same systems previously used. Reactions with the individual stereoisomers of MeCH=CHMeBr (thermal AIBN/n-BU3SnH conditions) afford a radical-equilibrated 96/4 E/Z ratio of vinylphosphonates. Substitution of (TMS)(3)SiH for n-Bu3SnH yields an approximately 1/1 ratio of separable E and Z vinylphosphonate diastereomers.
