(1-Trimethylsilanylmethyl-vinyl) esters are synthesised via Wittig-Horner reactions starting from methylenediphosphonic esters. The reactions of (1-trimethylsilanylmethyl-vinyl)-phosphonic esters with NsONHCO(2)Et and CaO, produce alpha -methylene N-(ethoxycarbonyl) beta -amino phosphonic esters, isolated up to 60% yield, through addition of(ethoxycarbonyl) amine function on the double bond and silyl group elimination.
