用闪光光解和产物分析方法研究了四苯基双膦、三苯基膦和二苯基膦在乙醇中的光化学反应。研究的所有三种膦的主要光化学过程似乎是形成二苯基氧膦基自由基，随后从溶剂醇中夺取α-H原子。考察了萃取速率常数与各种醇的α-H键能之间的关系。
The photochemical reactions of tetraphenyldiphosphine, triphenylphosphine, and diphenylphosphine in alcohol were studied by flash photolysis and product analysis. The primary photochemical process of all three phosphines studied appeared to be the formation of diphenylphosphinyl radicals which subsequently abstract α-H atoms from the solvent alcohol. The relationship between the rate constants of the abstraction and the α-H bond energies of various alcohols was examined.
