Kraynack, Erica A. published the artcileIntermolecular pinacol coupling of sulfur-substituted aldehydes by vanadium-zinc complex [V2Cl3(THF)6]2(Zn2Cl6). The effect of the substitution at sulfur on the stereochemical outcome of the coupling reaction, Category: catalysis-chemistry, the publication is Journal of Organic Chemistry (1993), 58(22), 6114-17, database is CAplus.
Pinacol cross-couplings of sulfur-substituted aldehydes with aliphatic aldehydes have been investigated. Addition of the sulfur aldehyde to a solution of [V2Cl3(THF)6]2(Zn2Cl6) and the aliphatic aldehyde provides unsym. 1,2-diols in good yield (55-97%). Stereoselectivity in these reactions is influenced by changing the substituent R3 in sulfonyl (R3SO2)-substituted aldehydes.
