Reaction of a number of 1,6-diene or enyne systems with TolSO2SePh, under free radical conditions, results in selenosulfonylation with concomitant C-C bond formation, to give cyclised alkyl or vinyl sulfones containing the synthetically useful phenylselen
Synthesis of Cyclobutanated Butyrolactones via Copper(I)-Catalyzed Intermolecular Photocycloadditions of Homoallyl Vinyl or Diallyl Ethers

Intramolecular copper(I)-catalyzed 2? + 2? photocycloaddition provides an effective route for the synthesis of 2-oxa- and 3-oxabicycloheptanes from homoallyl vinyl or diallyl ethers, respectively.Ruthenium-catalyzed oxidation of these multicyclic tetrahydrofuran products provides a novel annulation of cyclobutanated butyrolactones.For intermediates incorporating both methine and methylene groups next to the tetrahydrofuran oxygen, a remarkable selectivity was found for oxidation at the methylene position.Highly stereoselective generation of exo-2-alkylsubstituted 3-oxabicycloheptanes occurred upon photobicyclization of diallyl ethers bearing an α-alkyl substituent.
The Reaction of Bis(dimethylglyoximato)(pyridine)cobalt(I), Cobaloxime(I), with 2-(Allyloxy)ethyl Halides and the Photolysis of the Resulting Organo-cobaloximes

The reactions of 2-(allyloxy)ethyl halides with cobaloxime(I) gave (tetrahydro-3-furanyl)methylcobaloximes via an electron transfer from cobaloxime(I) to the halides to give radical anions.The rupture of a halide ion to give an organic radical and the ring closure to give a (tetrahydro-3-furanyl)methyl radical are followed by the radical coupling between the organic radical and the cobaloxime(II).The structures of the organocobaloximes were determined by the analyses of the photolysis products under aerobic or anaerobic conditions.
