Formation of Tetrahydrothiophenes via a Thia-Paternò-Büchi-Initiated Domino Photochemical Reaction

We have established photochemical access to thietane or tetrahydrothiophene compounds from thiobenzophenone derivatives and acrylonitrile, wherein the product selectivity is controlled by a simple adjustment of the reagent concentration in solution. Small libraries of five-membered ring sulfur-containing compounds were prepared through a thia-Paternò-Büchi reaction, followed by a previously unknown regioselective photochemical ring enlargement reaction in a domino process or a stepwise fashion. A mechanism is proposed to rationalize this ring enlargement reaction via a carbene species provided from photoexcited thiocarbonyl compounds.

A new, efficient and simple method for the thionation of ketones to thioketones using P4S10/Al2O3

A simple, efficient and new method has been developed for the synthesis of thioketones by thionation of ketones using P4S10/Al 2O3 in acetonitrile. It has been found that the P 4S10/Al2O3 combination provides a simple and convenient method for the synthesis of thioketones.

9-Fluorenyl 9-(p-Tolylsulfonyl)-9-fluorenyl Disulfide: The Unexpected Product of the Reaction of 9-Bromofluorene and Potassium p-Toluenethiosulfate and the Mechanism of Its Formation

Reaction of potassium p-toluenethiosulfonate with 9-bromofluorene leads, not to the expected 9-fluorenyl p-toluenethiosulfonate (3), but rather to a product shown to be 9-fluorenyl 9-(p-tolylsulfonyl)-9-fluorenyl disulfide (7, R = 9-fluorenyl) (eq 11).Thi
