tert-Butyldiphenylphosphine

Application

Tert-Butyldiphenylphosphine is developed as an integral component of the new family of Ph2(t-Bu)P phosphines, specifically designed to enhance the efficiency of several catalytic transformations. It serves as a key catalyst in Silyl-Heck transformations and plays a crucial role in various reaction processes. This includes acting as a catalyst in nickel/Lewis acid-catalyzed carbocyanation of alkynes with acetonitrile or its derivatives, facilitating palladium-catalyzed hydrocarboxylation of acetylene with carbon monoxide to produce acrylic acid under mild conditions, and forming a palladium-based catalyst for methoxycarbonylation reactions. Additionally, it is utilized in Ru-catalyzed transfer hydrogenation during the reductive coupling of disubstituted allenes with aldehydes and aids in stereoselective silylation through dehydrogenative Si-O coupling with Si-stereogenic silanes. As a phosphine ligand in nickel-catalyzed carbocyanation of alkynes and a monodentate P-donor ligand, tert-Butyldiphenylphosphine significantly contributes to advancing the field of catalyst design and application.
