and (t-Bu)3PH+BF4− (molar ratio 4 : 3 : 8) dispersed in H2N(i-Pr)2+Br− can be used as a “single source” precatalyst for the Sonogashira coupling of aryl bromides with various aryl- and alkylacetylenes in HN(i-Pr)2 solvent. Arylacetylenes require just 0.005 mol % of Pd catalyst at 80 °C, with TOFs ranging between 3,200 and 10,000 h−1.
