In the fall of 1972 I first heard the term "olefin metathesis" from
The olefin metathesis mechanism was one of my first projects at MSU and my group explored various aspects of this reaction throughout my career.
Although ring opening olefin metathesis polymerization,
Today metathesis is used in the pharmaceuticals, foodstuffs, chemical, biotechnical, polymer and paper industries.
They have become the first well-defined catalysts for general use in metathesis in ordinary laboratories, and new visions of the opportunities of organic synthesis have emerged from their use.
One of the most exciting of these processes was olefin metathesis.
(ROMP), provided the path into polymer science, the techniques learned have opened possibilities outside of olefin metathesis.
This problem has been driving me nuts for a while now because I can't for the life of me think of a possible example showing this kind of metathesis in the onset of a pre-IE verb stem.
The Leeds approach makes use of 'metathesis', a reaction that won the 2005 Nobel Prize in Chemistry.
