THE REACTION OF SULFINIC ACIDS WITH BENZENESELENINIC ACID

Aromatic sulfinic acids are rapidly oxidized at 0 deg C by benzeneseleninic acid, setting in motion a reaction sequence whose final products are (a) the arenesulfonate salt of benzeneseleninic acid (2) and (b) the Se-phenyl areneselenosulfonate (1).

Alkene: Versus alkyne reactivity in unactivated 1,6-enynes: Regio-And chemoselective radical cyclization with chalcogens under metal-And oxidant-free conditions

Herein, we have developed metal and oxidant-free visible light-promoted alkene vs. alkyne regio-And chemoselective radical cascade cyclization of electronically unbiased 1,6-enynes with chalcogens to synthesize substituted pyrrolidines bearing chalcogens. The reaction generated three new bonds, namely, C-SO2, C-C, and C-Se under extremely mild conditions. Furthermore, we achieved regio-And chemoselective mono-addition of aromatic thiophenols with unactivated 1,6-enynes. The key features of this protocol are broad substrate scope, environment-friendly conditions, operational simplicity, atom economy, and amenability to gram-scale synthesis. The mechanistic studies corroborate that the reaction proceeds via a radical pathway.

Metal-free difunctionalization of alkynes to access tetrasubstituted olefins through spontaneous selenosulfonylation of vinylidene: Ortho -quinone methide (VQM)

A metal-free difunctionalization of alkynes to access tetrasubstituted olefins through spontaneous selenosulfonylation of vinylidene ortho-quinone methide (VQM) was described herein. The reaction was conducted under mild conditions without any catalysts or additives. Preliminary mechanism studies revealed that the formation of VQM was the key for this alkyne di-functionalization reaction. The reaction could be applied in the enantioselective asymmetric synthesis of axially chiral styrene. Furthermore, the selenosulfonylation adducts can be transformed into useful naphtho[2,1-b]furan and benzofuran scaffolds.
