EFFICIENT SYNTHESIS OF [2]ROTAXANES BASED ON SEQUENTIAL ACETYLENE-DICOBALT HEXACARBONYL COMPLEXATION AND STOPPER MODIFICATION

摘要

This paper describes an efficient end-capping method for the preparation of [2]rotaxanes, using acetylene-dicobalt hexacarbonyl complexation and subsequent transformation of the complexes into a series of vinylsilanes though hydrosilylation.
