α-Lithiosulfinyl carbanions react either intermolecularly, after transmetalation into an organocopper derivative in an SN2-type process, with zinc carbenoids, or intramolecularly by higher-order zincates through a tandem zinc homologation–β-elimination reaction into the corresponding alkenes. α,α- and α,β-Disubstituted alkenes can also be produced through these two methodologies.(© Wiley-VCH Verlag
α-硫代亚硫酰基碳负离子在 SN2 型过程中金属转移成有机铜衍生物后,与类锌化合物发生分子间反应,或者通过串联锌同系化 - β-消除反应与高阶锌酸盐发生分子内反应,生成相应的烯烃。α,α- 和 α,β-双取代烯烃也可以通过这两种方法生产。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
