A practical method for the construction of stilbene derivatives has been developed via catalytic cross-coupling of cinnamic acids with aryl triazenes. The methodology offers high stereoselectivity and is endowed with broad substrate scope, high yield, and significant functional group tolerance.

The straightforward visible-light-induced synthesis of stilbene compounds via the cross-coupling of nitroalkenes and diazonium tetrafluoroborates under transition-metal-free conditions is described. The protocol uses green LEDs as light sources and eosin Y as an organophotoredox catalyst. Broad substrate scope and exclusive selectivity for the (E)-configuration of stilbenes are observed. This protocol proceeds via a radical pathway, with nitroalkenes serving as the radical acceptor, and the nitro group is cleaved during the process.

The reaction of the lithium derivatives of N,N,N',N'-tetramethyldiamides of arylmethanophosphonic acids (1-Li) with ortho- and para-substituted benzaldehydes 2 is studied.Reaction conditions are found for erythro-stereoselective addition of 1 to 2 with high diastereomeric purity (95-99percent) of the rythro adducts 3, 4 (yields 35-72percent).By thermolysis of the adducts in neutral medium the corresponding (Z)-ortho and para-substituted silbenes 5, 6 are obtained.Some factors causing the predominant formation of the erythro adducts 3, 4, as well as the influence of the ortho-substituents on the equilibrium are discussed.
