Abstract: | Tetrabutyl-1,3-diacyloxydistannoxanes, (RCOO)Bu2SnOSnBu2(OOCR) (A) and/or tetrabutyl-1-acyloxy-3-hydroxydistannoxanes, (RCOO)Bu2SnOSnBu2(OH) (B), can be prepared from equimolecular amounts of dibutyldiallyltin and carboxylic acid, RCOOH (R = H, CH3, CH2Cl, CHCl2, CCl3, CF3) in moist methanol or acetone/water (50/50, v/v). Isolation of compounds (A) or (B) depends upon the hydrolyzing power of the medium and the nature of R. |
