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.
