Bis(triphenylphosphine)(maleic anhydride) palladium(0) can be used as a zero-valent palladium complex to catalyze the dimerization of 1,3-dienes and 1,2-dienes.
Reaction of Tetrakis(triphenylphosphine)palladium(0) with Maleic Anhydride at rt in benzene, benzene/THF, or THF3 yields the title complex as a stable monomeric species, which is purified by crystallization from methanol/hexane. Bis(triphenylphosphine)(maleic anhydride) palladium(0) has also been synthesized from the putative bis(triphenylphosphine)palladium.
