Herein, we report a catalytic system based on the earth‐abundant manganese for the
ketone, amine, alkyne (KA2) reaction. The efficiency of manganese manifests at relatively …

Metal-catalyzed hydrocarbofunctionalizations of alkynes or alkenes are well established. In
contrast, metal-free strategies have few precedents. We report herein a multicomponent …

A new TBHP/TBAI-mediated reaction of propargyl alcohols with sulfonyl hydrazides in the
presence of HOAc has been established, in which a wide variety of allenyl sulfones were …
