Introduction
Organic phosphines and derivatives are a class of organic compounds that contain a carbon-phosphorus (C-P) bond. These compounds are derived from phosphine (PH3), where one or more hydrogen atoms are replaced with organic substituents. Known for their versatile applications, these compounds and their derivatives are vital in both academic research and industrial processes. They are widely used in various fields, including organic chemistry, catalysis, materials science, and pharmaceuticals.
Applications
