Richard Royce Schrock (born January 4, 1945) is an American chemist and Nobel laureate recognized for his contributions to the olefin metathesis reaction used in organic chemistry.

[8] In 2018, Schrock joined the faculty of his alma mater, the University of California, Riverside, where he is now the Distinguished Professor and George K. Helmkamp Founder's Chair of Chemistry.

[10][11][12][13] Many supporting ligands have been explored in efforts to better understand the nature of the single molecule catalysts, most notably 2,6-diisopropylphenylimido and adamantylimido, as well as various tert-butyl alkoxides with varying degrees of fluorination.

Schrock's work is ongoing with goals of furthering the understanding of metathesis selectivity, developing new catalyst architectures, and elucidating how alkylidenes and alkylidynes are formed naturally from olefins.

In 2005, Schrock received the Nobel Prize in Chemistry, with Robert H. Grubbs and Yves Chauvin, for his work in the area of olefin metathesis, an organic synthesis technique.
