Representative examples of Sonogashira couplings using (n-Bu2N)3P as the ligand on Pd Similar uses of the same Pd complex of (n-Bu2N)3P in Suzuki-Miyaura couplings, as illustrated in Scheme 3, also gave good levels of cross coupling products. In addition to relatively straightforward cases, an example of a highly substituted substrate underwent an efficient coupling affording the product in 88% yield.
