Either silver trifluoromethanesulfonate or a mixture of gold(I) chloride, silver trifluoromethanesulfonate, and triphenylphosphine catalyze the formation of pyrroles from substituted beta-alkynyl ketones and amines. The reactions proceed by using 5 mol % of catalyst with yields of isolated pyrroles ranging from 13% to 92%. Sixteen examples are used to compare the effectiveness of each catalyst.
三氟甲磺酸银或氯化金（I）、三氟甲磺酸银和三苯基膦的混合物均可催化由取代的β-炔基酮和胺形成吡咯。反应使用5 mol%的催化剂进行，分离得到的吡咯产率为13%至92%。用16个实例比较了每种催化剂的效果。
