latter is inert toward the second molecule of pyridine under the used conditions. Compound I was found to react with triphenylphosphine to form a mixture of 3-triphenylphosphoniumbromidopropionitrile II and 1-triphenylphosphoniumbromido-2-pyridiniumbromidoethane III. Schemes of reactions were suggested involving attack of phosphine on the carbonyl group as the first stage. The reaction of α-bromoacrylic
