Chemical transformations of cis-W(CO)4(C5H 5N)2 in the ring-opening metathesis polymerization of norbornene

The six-coordinate W0 complex cis-W(CO)4(C 5H5N)2 has been found to be active in the in situ formation of a carbene species from norbornene, which generates a typical ring-opening metathesis product (ROMP). A proposed mechanism of initiation suggests that the reaction involves a 2,3-hydrogen shift in the coordinated norbornene (η2 → η1). The initiating carbenoid group is identified from the products of the spontaneous carbene-CO coupling and Wittig reactions test. Formation of W(CO)3(η 6-C6H5CH3) when toluene is the solvent, followed by reaction with the carbene, is blamed for catalyst deactivation.

A series of benzyl carbinols have been reacted with HSO3F at -78 deg C, the solutions quenched, and the products isolated and identified.A variety of reaction modes occur including reduction (3-methyl- and 4-methyl-1-benzylcyclohexanol), rearrangement and
