Malcolm Leslie Hodder Green FRS FRSC[4] (16 April 1936 – 24 July 2020)[5] was Professor of Inorganic Chemistry at the University of Oxford.

Green's earliest publications described metal-hydride and metal-olefin complexes,[9] themes that he pursued throughout his career.

Many of his early contributions focused on the chemistry of molybdocene dihydride ((C5H5)2MoH2) and the related tungsten derivative.

This work would later lead to the so-called "modified Green-Rooney mechanism" for Ziegler–Natta catalysis, wherein agostic interactions guide the stereochemistry of the alkene insertion step.

[11][12] Towards the end of his career Green's interests shifted to include studies of carbon nanotubes, developing methods to "uncap" (open) them,[13] and investigating their filling with metals and with salts.
