Comparative Study of the Water-Catalyzed Hydrolysis of methyl Perchlorate in 1,4-Dioxane-Water and in 1,3-Dioxane-Water

Pseudo-first-order rate constants (kobsd) and thermodynamic activation parameters have been compared for the water-catalyzed hydrolysis of H2O = 0.80 and most likely reflect the specific hydrogen bonding interactions between water and the organic cosolvent.The structural properties of both aqueous binaries are critically discussed, and it is concluded that the maxima inkobsd at about nH2O = 0.80 in both solvent mixtures do not reflect an enhanced degree of water structure at this solvent composition.

tert-Butyl Hydroperoxide-Initiated Radical Cyclization of 1-(Allyloxy)-2-(1-Arylvinyl)Benzenes with Sulfinic Acids to Access Sulfonated Benzoxepines

A tert-butyl hydroperoxide-initiated radical cyclization of 1-(allyloxy)-2-(1-arylvinyl)benzenes with sulfinic acids for the construction of sulfonated benzoxepines is developed. This reaction involves a radical pathway and offers a straightforward route to the formation of seven-membered ring via sulfonylation/cyclization process. This methodology features mild reaction conditions, a broad substrate scope and good functional group tolerance. (Figure presented.).

A General, One-Pot Method for the Synthesis of Sulfinic Acids from Methyl Sulfones

A simple and efficient method for converting methyl sulfones to sulfinic acids is described. The process involves alkylation with a benzylic halide, followed by in situ elimination of the resulting styrene in the presence of excess base to yield a sulfinic acid in a single reaction process. The usefulness of the alkylation-elimination sequence is demonstrated by generating a variety of sulfinic acids from methyl sulfones. Late stage functionalization and 14C-labeling of several biologically active methyl sulfones were accessed via sulfinate intermediates.
