The structure of the adduct between maleic anhydride and triphenylphosphine has been determined by direct synthesis and spectral analysis. It is analogous to a phosphine methylene derivative (WITTIG reagent) stabilized by an u-carbonyl group. With aldehydes, it gave none or very poor yields of the expected olefins; water (or alcohols) caused the anhydride ring to open, instead of forming triphenylphosphine
通过直接合成和光谱分析已经确定了马来酸酐和三苯基膦之间的加合物的结构。它类似于通过u-羰基稳定的膦亚甲基衍生物(WITTIG试剂)。使用醛时,预期烯烃的收率不高或非常差。水(或醇)导致酸酐环打开,而不是形成三苯膦氧化物加相应的烃。
