Abstract
The alpha,beta-unsaturated bimetallic Fischer carbene complex 1, (CO)5 WC(OTiCP2Cl)(C(CH3)=CH2), undergoes reaction with cyclopentadiene to g ive predominantly the exo Diels-Alder adduct in high yield; X-ray crys tal structures and molecular mechanics calculations for both reactant and product complexes suggest that the reaction may be controlled by s teric factors.
