Functionalized triaryl- and diarylalkylphosphines are accessible in high yields following a mild fluoride catalyzed phosphorousâcarbon coupling protocol starting from fluoroarenes and silylated phosphines. The reaction requires a minimum of solvent and can be applied to the synthesis of several functionalized phosphines on a kilogram scale without problems. In contrast to the phosphine synthesis in a superbasic medium, there is no salt formation during the reaction which simplifies the work-up process.
