Abstract
The coupling of [3]-ferrocenophan-1-one 1 with McMurry type reagents to yield olefins E,Z-bis([3]-ferrocenophane-1-ylidene) 2a,b is described. In the case of the TiCl3/Zn reagent only pinacol rearrangement to complex 3 subsequent to coupling takes place in high yield. In contrast, upon addition of pyridine the reaction proceeds to the olefins in high yield. The X-ray structure of 3 and the electrochemistry of the olefins 2a,b is described.
