Cobalt-catalyzed regio- and stereoselective intermolecular enyne coupling: An efficient route to 1,3-diene derivatives

The reaction of alkynes with vinyl arenes or vinyl trimethyl silane in the presence of a cobalt(II) complex, Zn and ZnI2 in CH 2Cl2 at rt to 50 °C provides 1,3-dienes in good to excellent yields. The Royal Society of Chemistry 2010.

Rhodium-catalyzed regio- and stereoselective codimerization of alkenes and electron-deficient internal alkynes leading to 1,3-dienes

(Chemical Equation Presented) A cationic rhodium(I)/H8-BINAP complex catalyzes codimerization of alkenes bearing no r-hydrogen and electron-deficient internal alkynes, leading to 1,3-dienes in good yields with moderate to excellent regio- and stereoselectivity. The same complex also catalyzes codimerization of an acrylate and phenyl-substituted electron-rich internal alkynes, leading to 1,3-dienes.

On the origin of regioselectivity in the photorearrangement of 4,4-diphenyl-2,5-cyclohexadiene systems. Synthesis and photochemistry of 4,4-diphenyl-γ-thiopyran and -γ-thiopyran-1,1-dioxide

The synthesis from diphenylmethane of 4,4-diphenyl-γ-thiopyran and 4,4-diphenyl-γ-thiopyran-1,1-dioxide is described.Upon direct photolysis at 254 nm the γ-thiopyran derivative undergoes rearrangement to a mixture of 5,6-diphenyl-2-thiabicyclohexen
