As shown by kinetic and product analysis, the solvolysis of7 and 8 in m includes several competitive reactions, one of them being neighbofing sulfur participation and formation of intermediate cyclic sulfonium cation. Recently we have demonstrated' the absence of r-or n-participation in solvolysis o

A study of the influence of 6-endo substituents on the reactivity of 2-exoand 2-endo-norbornyl p-toluenesulfonates 3 and 4, respectively, confirms that polar rather than steric effects control relative rates.

The condensation of aryl methyl ketones 6 with acetic anhydride 4a in the presence of the boron trifluorideacetic acid adduct 7 gives rise to the formation of 4aryl-2,2-difluoro-6-methyl-1,3,2-(2H)-dioxaborines 8 in satisfactory yields. The stable 4-aryl-2,2-difluoro-6methyl-1,3,2-(2H)-dioxaborines
