Abstract: A convenient method for preparing cinnamides and their derivatives via condensationof telluronium salts with corresponding aldehydes is reported.The effects of solvents andbases on the condensation were studied.The yields were 82~97%.All products are the E-and E,E-isomers as confirmed by their m.p., IR and 1H NMR spectra.

Key words: telluronium salt, telluronium ylide, cinnamide aldehyde, condensation
