研究了醋酸苯汞与亚磷酸三乙酯或三正丁基膦的反应。此外，还研究了以二苯汞和三正丁基膦为原料制备酸酐的新方法。两摩尔羧酸与一摩尔二苯汞和一摩尔三正丁基膦反应，生成相应的高产羧酸酸酐以及汞、苯和氧化三正丁基膦。同样，用两摩尔磷酸单酯或磺酸与二苯汞和三正丁基膦各一摩尔反应，可以高产得焦磷酸盐或磺酸酸酐。讨论了这些反应的机理。
The reactions of phenylmercuric acetate withtriethyl phosphite or tri-n-butylphosphine have been investi-gated. Further, a novel method for the preparation of acid anhydrides by means of diphenylmercury and tri-n-butylphosphine has been studied. The reactions of two moles of carboxylic acids with one mole each of diphenylmercury and of tri-n-butylphosphine gave the corresponding carboxylic acid anhydrides in high yields along with mercury, benzene, and tri-n-butylphosphine oxide. Similarly, pyrophosphates or sulfonic acid anhydride were prepared in high yields by the reactions of two moles of phosphoric monoesters or sul-fonic acid with one mole each of diphenylmercury and of tri-n-butylphosphine. The mechanisms of these reactions are discussed.
