Single step synthesis of an ethynylferrocenyl-[4]-ferrocenophane

Abstract : A single step preparation of a novel [4]-ferrocenophane containing an ethynyl-ferrocene directly connected to the unsaturated heteroannular bridge starting from 1,10-diformyl-ferrocene is reported. The suggested mechanism involves the reaction of water with the unstable diethynyl-ferrocene intermediate. The crystallographic structure of this multi-functional molecule has been resolved.
