The synthesis of [2]rotaxanes without polar functional groups was achieved by protodesilylation of the corresponding phenylene-bridged 1,12-disilacyclodocosanes in 20–30% isolated yields. The molecular structure of rotaxane 1a showed that the wheel is not at the center of the rod but on a dimethylene group of the dumbbell. By detailed NMR analyses, facile shuttling of the wheel was found to control the geometry of the dumbbells in the rotaxanes.
