The (Z)/(E) composition of olefinic alcohols produced by sodium ring-scission of cyclic β-halogeno-ethers can be accounted for by a mechanism involving fast electron transfer and carbanion inversion, with ring-cleavage speedier than conformational inversion.
环状β-卤代醚的钠环断裂产生的烯烃醇的(Z)/(E)组成可以通过涉及快速电子转移和碳负离子转化的机制解释,其中环裂解的速度比构象转化快。
