Tetraphenyldiphosphine and aliphatic carboxylic acids at 180° give 1-hydroxy-1,1-bisdiphenylphosphinylalkanes which slowly rearrange to 1-diphenylphosphinyloxyalkyldiphenylphosphine oxides. The acids Ph·X·CH2·CO2H (X = O or S) also give the esters Ph2P(:O)XPh. Di- and tri-phenylacetic acids give only di- and tri-phenylmethanes with the formation of carbon monoxide.
在180°下,四苯基二膦和脂肪族羧酸得到1-羟基-1,1-双二苯基膦基烷烃,它们缓慢地重排为1-二苯基膦酰氧基烷基二苯基膦氧化物。酸Ph·X·CH 2 ·CO 2 H(X = O或S)也可得到酯Ph 2 P(:O)XPh。二苯乙酸和三苯乙酸仅生成二苯甲烷和三苯甲烷,并形成一氧化碳。
