A green approach was proposed for the synthesis of 2-chloroprop-2-en-1-yl sulfones in 47–94% yield. The molecular and crystal structures of 2-chloroprop-2-en-1-yl phenyl sulfone and 2-chloroprop-2-en-1-yl methyl sulfone were determined by X-ray analysis.

A Cu-catalyzed cascade oxidative radical process of β-keto sulfones with alcohols has been achieved by using oxygen as an oxidant. In this reaction, β-keto sulfones were converted into sulfinate esters under the oxidative conditions via cleavage of C?S bond. Experimental and computational studies demonstrate that a new pathway is involved in this reaction, which proceeds through the formation of the key four-coordinated CuII intermediate, O?O bond homolysis induced C?S bond cleavage and Cu-catalyzed esterification to form the final products. This reaction provides a new strategy to sulfonate esters and enriches the research content of C?S bond cleavage and transformations.

The use of (alkylthio)- and alkoxy-1,2,4-triazines in intermolecular inverse electron demand Diels-Alder reactions with enamine and enaminone dienophiles leads to highly functionalized pyridine derivatives.
Intramolecular rhodium carbenoid insertions into aromatic C-H bonds. Preparation of 1,3-dihydrothiophene 2,2-dioxides fused onto aromatic rings

, p. 1071 - 1076 (2007/10/02)
The preparation of 1-carboalkoxy-1,3-dihydrobenzenothiophene 2,2-dioxides via rhodium acetate or rhodium trifluoro-acetate catalyzed decomposition of α-diazo-β-arylmethanesulfonyl esters is described.The reaction has been extended to yield 1,3-dihydrothiophene 2,2-dioxides fused to the 2,3 position of thiophene and indole, but not of furans.In the latter case products derived from the opening of the furan ring were obtained.Key words: synthesis, 1-carboalkoxy-1,3-dihydrobenzothiophene 2,2-dioxides, intramolecular carbenoid insertions, rhodium acetate catalysis.
AN UNUSUALLY FACILE DIELS-ALDER REACTION WITH NOVEL 6-ALKYLTHIO DERIVATIVES OF 1,2,4-TRIAZINE

Treatment of a series of 6-alkylthio-, 6-alkylsulfinyl and 6-alkylsulfonyl-1,2,4-triazines with 1-pyrrolidinocyclopentene yields 3,4-cyclopentenopyridines.The observed rates of these cycloaddition reactions (sulfide sulfoxide sulfoxide) are consistent
