Temperature factor was found to be determining in the isomerization of 2-carboxyprop-1-en-1-yl-and 2-carboxyprop-2-en-1-yl(triphenyl)phosphonium bromides. Elevated temperature favors formation of isomer with the double bond in the β,γ position with respec

α-Chloroacrylic acid reacts with triphenylphosphine to give (E)-(2-carboxyvinyl)triphenylphosphonium chloride. The same reaction with β-halomethacrylic acids yields, depending on the temperature, either (2-carboxypropenyl)triphenylphosphonium halides or t
