title: The effect of steric bulk in Sonogashira coupling reactions.
abstract: The rates of Sonogashira coupling reactions using [Pd-PR(3)] complexes depend on a combination of the steric bulk of phosphines and substrates; however, below a critical cone angle of ca. 170 degrees the catalytic activity drops drastically.
