Schepmann and Michelle Mynderse. Journal of Chemical Education , 87 7 , Eric J. In this process, two olefins compounds with a carbon—carbon double bond were converted into two new olefins in the presence of catalysts prepared from tungsten, molybdenum, or rhenium oxides supported on silica or alumina.
This reaction known as metathesis is used in multimillion industrial processes in the petrochemical and pharmaceutical industries and for high-strength materials. An analogous reaction for carbon-carbon triple bonds was discovered some years later.
Several decades were required to unravel the related mechanisms for these olefin and acetylene metathesis reactions. This was done largely through the synthesis of new types of organometallic compounds and the synthesis and study of homogeneous catalysts for each reaction.

Today a wide variety of reactions that cannot be achieved catalytically with traditional organic chemistry are based on carbon—carbon double or to a lesser extent triple bond metathesis reactions. He was born in the humble Indiana farming community of Berne where his carpenter father owned a woodworking shop.
