Hydroxycarbonylation of Alkenes with Formic Acid Catalyzed by a Rhodium(III) Hydride Diiodide Complex Bearing a Bidentate Phosphine Ligand | Organometallics - ACS Publications
An improved catalytic system was developed for the Rh complex-catalyzed hydroxycarbonylation of alkenes using formic acid (HCOOH). Ligand screening revealed DPEphos, a bidentate phosphine ligand, to ...
Government Bans More Than 1% Palladium, Rhodium & Iridium Alloy, Imposes Restrictions To Balance Trade Facilitation
The government imposed import curbs on certain colloidal precious metals. The illegal flow of gold in India in liquid form is a major problem. If the import of palladium, rhodium, and iridium alloy ...
