Trialkylphosphines react with equimolar amounts of sulfur trioxide to form the 1:1 adducts R3P⊕–SO3\ominus. Trialkylarsines and -stibines undergo sulfur trioxide insertion reactions across the metal-carbon bond to give the trisulfonates of the metal M(OSO2R)3 (M=As, Sb). The reactions of trialkyl phosphites, with sulfur trioxide yield trialkyl phosphates, trialkyl thiophosphates, dialkyl alkylphosphonates
三烷基膦与等摩尔量的三氧化硫反应形成 1:1 的加合物 R3P⊕–SO3\ominus。三烷基胂和-锑通过金属-碳键发生三氧化硫插入反应,得到金属M(OSO2R)3 (M=As, Sb) 的三磺酸盐。亚磷酸三烷基酯与三氧化硫反应生成磷酸三烷基酯、硫代磷酸三烷基酯、烷基膦酸二烷基酯、硫酸二烷基酯和含有磷原子的聚合物。三烷氧基胂和锑的反应导致三氧化硫插入金属-氧键形成烷氧基金属烷基硫酸盐 (RO)3−nM(OSO3R)n (M=As, Sb; n=1, 2, 3)取决于所用试剂的化学计量比。金属硫酸盐的热解得到二烷基硫酸盐和含有金属的不可蒸馏的残余物。
