Hirokazu Narita,Rebecca M. Nicolson,Ryuhei Motokawa,Fumiyuki Ito,Kazuko Morisaku,Midori Goto,Mikiya Tanaka,William T. Heller,Hideaki Shiwaku,Tsuyoshi Yaita,Ross J. Gordon,Jason B. Love,Peter A. Tasker,Emma R. Schofield,Mark R. Antonio,Carole A. Morrison +15 more
TL;DR: A consistent and comprehensive understanding of how the ligand operates to achieve Rh(III) selectivity over the competitor anion Cl- has emerged and thus offers promise for improving the sustainability of metal extraction from both traditional mining sources and the recycling of secondary source materials.
