Abstract

Synthetic routes to two molecular motors are reported. The sterically hindered central olefinic bond connecting the two halves of these C 2-symmetric molecules was prepared by a McMurry reaction. In this way, a motor with two five-membered rings and a motor with two six-membered rings were prepared, both with two versatile methoxy substituents at positions not interfering with the rotary behavior.
