WebDec 15, 2024 · 1. Introduction Phosphines are ubiquitous ligands, with a wealth of history and rich metal coordination chemistry. Much of modern day homogeneous transition metal catalysis is underpinned by phosphine ligands and metal–phosphine coordination complexes such as Wilkinson's, 1 Crabtree's, 2 and Grubbs's 3 catalysts, and Vaska's … Webphosphine (PH3), also called hydrogen phosphide, a colourless, flammable, extremely toxic gas with a disagreeable garliclike odour. Phosphine is formed by the action of a strong base or hot water on white phosphorus or by the reaction of water with calcium phosphide (Ca3P2). Phosphine is structurally similar to ammonia (NH3), but phosphine is a much … WebPhosphine affects the small peripheral vessels, causing a profound decrease in systemic vascular resistance.
