Abstract
The thermolysis of diphenylzirconocene in the presence of 1,4-diphenyl-1,3- butadiyne to yield the seven-membered zirconacyclocumulene 1 via the interm ediacy of benzynezirconocene is described. This complex has been characteri zed by an X-ray diffraction study. Additionally, better knowledge of the bo nding of the cumulene moiety was achieved by DFT calculations. Cleavage of the Zr-C bonds of 1 with methanol provided the corresponding butatriene 2.
