Trialkylphosphines react with equimolar amounts of sulfur trioxide to form the 1:1 adducts R<SUB>3</SUB>P<SUP>⊕</SUP>–SO<SUB>3</SUB><SUP>\ominus</SUP>. Trialkylarsines and -stibines undergo sulfur trioxide insertion reactions across the metal-carbon bond to give the trisulfonates of the metal M(OSO<SUB>2</SUB>R)<SUB>3</SUB> (M=As, Sb). The reactions of trialkyl phosphites, with sulfur trioxide yield trialkyl phosphates, trialkyl thiophosphates, dialkyl alkylphosphonates, dialkyl sulfates, and polymers which contain phosphorus atoms. The reactions of trialkoxyarsines and -stibines result in the insertion of sulfur trioxide across the metal-oxygen bond to form the alkoxymetal alkylsulfates (RO)<SUB>3−<I>n</I></SUB>M(OSO<SUB>3</SUB>R)<I><SUB>n</SUB></I> (M=As, Sb; <I>n</I>=1, 2, 3) depending on the stoichiometric ratios of the reagents used. Pyrolysis of the metal sulfates gives dialkyl sulfates and undistillable residues containing the metals.
