- Reactions of Group V Metal Compounds with Sulfur Trioxide
-
Trialkylphosphines react with equimolar amounts of sulfuric trioxide to form the 1:1 adducts R3P(1+)-SO3(1-).Trialkylarsines and -stibines undergo sulfur trioxide insertion reaction 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 phosphonates, trialkyl thiophosates, 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)3-nM(OSO3R)n (M=As,Sb; n=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.
