A Molecularly Defined, Grafted Olefin Metathesis Catalyst from Tris(neopentyl)‐nitridomolybdenum(<scp>VI</scp>)

Abstract

1,2-Addition of the surface silanol groups on SiO2 to the nitridomolybdenum fragment of the title compound and subsequent α-elimination of neopentane forms the catalytically active surface species I. This is the first case in which an alkylated complex is converted into a heterogeneous catalyst in a well-defined way. The immobilized compound is significantly more active in ring-opening metathesis polymerization than the molecular precursor.
