Toxylic acid reacts with triphenylphosphine under soft conditions to
give betaine I, which is unstable and under heating or keeping elimi-
nates CO2 with the formation of phosphonium salt II.
SCHEME 1
Reaction of triphenylphosphine with fumaric acid carries out at high
temperature only, and in this reaction the previously described triph-
enylphosphonium ethylcarboxylate, stabilized by the molecule of ace-
tonitrile, has been directly obtained. The structure of all products has
been strictly confirmed by the direct method of x-ray analysis.
