(1) to the trans-isomer (2) and the rearrangement of 1-alkoxy-3-methylenecyclobutanes (4) and (8) to (6) and (10), respectively, are modestly accelerated by the presence of alkoxy groups compared to those of the related hydrocarbons; the effect of the alkoxy group in these reactions is, however, much smaller than that in the analogous cyclopropane rearrangements.
顺式-1,2-二甲氧基环丁烷(1)的几何异构化为反式异构体(2)和1-烷氧基-3-亚甲基环丁烷(4)和(8)的重排至(6)和(10)与相关烃的烷氧基相比,烷氧基的存在分别适度地促进了它们的形成;然而,在这些反应中烷氧基的作用比在类似的环丙烷重排中的作用小得多。
