چکیده

An efficient synthesis of vinylphosphonates is described. This involves the reaction of alkyl cyanoformates and dialkyl acetylendicarboxylates in the presence of trialkyl phosphites. The ¹H, ¹³C NMR, and ³¹P NMR spectra of vinylphosphonates having different substitution are consistent with the presence of two geometrical isomers.
