The high-yielding synthesis of novel N-acyl phosphonates with unprecedented structure was carried out by a homogeneous carbonylation reaction under mild reaction conditions. The palladium-catalysed aminocarbonylation of iodoalkenes (1-iodo-cyclohexene, 1-iodo-4-tert- butyl-cyclohexene, 1-iodo-2-methyl-cyclohexene and α-iodostyrene) with diethyl α- aminobenzyl-phosphonate as N-nucleophile resulted in the exclusive formation of ...
