A microwave-assisted approach for the synthesis of α-fluoro-α,β-unsaturated esters from ethyl bromofluoroacetate, aldehydes, and triphenylphosphine in the presence of Zn-Cu undersolvent-freeconditions was achieved. The reaction was accomplished within five minutes with good product yields.

During the treatment of ethyl alpha-fluoro-alpha-iodoacetate with aldehydes in the presence of tri-n-butylarsine and a catalytic amount (10 mol%) of Pd(PPh3)4, the aldehydes were eventually completely consumed and alpha-fluoro-alpha,beta-unsaturated esters were obtained in 52-90% yield.
