Maurice S. Brookhart (born 1942) is an American chemist, and professor of chemistry at the University of Houston since 2015.

He received his PhD in 1968 from the University of California, Los Angeles, in physical organic chemistry where his thesis advisor was Saul Winstein.

A recent major thrust has been the development of post-metallocene catalysts based upon late transition metal (Ni and Pd) complexes for olefin coordination polymerization.

[6][7][8] They carry out their mechanistic investigation of the polymerization reactions primarily by low temperature IR and NMR spectroscopies.

They have successfully demonstrated catalysis of the ortho-alkylation of aromatic ketones, alkyl aldehyde isomerization, hydroacylation, and the dehydrogenation of alkoxy silanes to generate silyl enol ethers.
