The elimination of thiocyanic acid from the stereoisomers of the hex-3-ene-2,5-diyl dithiocyanates, 4a, 4b, 6a and 6b, in the presence of a strong neutral base in an organic solvent, yields mixtures of the hex-2,4-dien-2-yl thiocyanates 9, 10 and 11via a preferentially syn process.
在强中性碱存在下,在有机溶剂中消除己-3-烯-2,5-二基二硫氰酸盐 4a、4b、6a 和 6b 立体异构体中的硫氰酸,通过优先合成过程得到己-2,4-二烯-2-基硫氰酸盐 9、10 和 11 的混合物。
