One-pot reactions of diorganotin oxides, R2SnO, with dimethyl sulfite under reflux conditions (125-127 °C) proceed via the Arbuzov rearrangement at the sulfur center, yielding the corresponding methoxydiorganotin methanesulfonates, R2Sn(OMe)OS(O)2Me [R = n-Pr (1), n-Bu (2), i-Bu (3), c-Hx (4)], as white, hygroscopic solids. These compounds react with β-diketones [acetylacetone (Hacac), benzoylacetone (Hbzac), and dibenzoylmethane (Hbzbz)] to afford mixed-ligand organotin derivatives, R2Sn(X)OS(O)2Me [X = acac, R = n-Pr (5), n-Bu (6); X = bzac, R = n-Pr (7), n-Bu (8); X = bzbz, R = n-Pr (9), n-Bu (10), i-Bu (11)]. Selective hydrolysis of the Sn-OMe bond in 1-3 occurs, resulting in the isolation of (μ-hydroxo)diorganotin methanesulfonates, R2Sn(OH)OS(O)2Me [R = n-Pr (12), n-Bu (13), i-Bu (14)]. All the compounds are characterized by elemental analyses and IR, multinuclear (1H, 13C, and 119Sn) NMR, and mass spectra. Unequivocal evidence of the presence of the methanesulfonate group is provided by the X-ray crystal structures of 6, 10, and 13. [For 6: trigonal space group R3? (No. 148), a = 28.664(1) A?, c = 13.056(1)A?, Z = 18. For 10: triclinic space group P1? (No. 2), a = 13.056(3) A?, b = 14.062(3) A?, c = 16.282(3) A?, Z = 4. For 13: triclinic space group P1? (No. 2), a = 9.089(2) A?, b = 12.040(2) A?, c =13.894(2) A?, Z = 2]. For 6 and 10, the solid-state structural analyses reveal dimeric structures with a bridging bidentate methanesulfonate group forming a centrosymmetric eight-membered ring. Compound 13 possesses a polymeric sheet structure with repeating 20-membered macrocycles (including two four-membered [Sn(OH)]2 rings) by virtue of the bridging bidentate methanesulfonate groups. A search for a possible pathway to give Arbuzov-rearranged products 1-4 leads us to speculate that there is an initial catalytic transformation of dimethyl sulfite to methyl methanesulfonate via intermediate compounds, Bu2Sn(OMe)2 (A) and [Bu2SnOMe]2O (B). A and B subsequently react with methyl methanesulfonate to give 1-4.
