A desulfonylative homocoupling of benzylic sulfone derivatives through a photoredox Ir catalyst is described. The 3,5-bis(trifluoromethyl)phenyl group is an effective substituent on sulfonyl group in this reaction, providing the structurally diverse

High enantioselectivities (94–96% ee) were obtained for the inverse electron-demand 1,3-dipolar cycloadditions between cyclohexyl vinyl ether and 2-benzopyrylium-4-olate generated via Rh₂(OAc)₄-catalyzed decomposition of o-methoxycarbonyl-α-di

We have found the first successful example of reverse-electron-demand dipole-LUMO/dipolarophile-HOMO controlled cycloaddition reactions between carbonyl ylides, which were generated from o-methoxycarbonyl-alpha-diazoacetophenone and their acyl deriva

The reaction of activated olefins with carbonyl ylides, generated by Rh-catalyzed decomposition of the corresponding α-diazocarbonyl compounds, is investigated in the presence of transition metal triflates and Pybox or BINIM-type ligands as catalyst
