A highly regioselective protocol for intermolecular thiocyanation-amination of alkynes by N-thiocyano-dibenzenesulfonimide (NTSI) as the SCN and nitrogen sources has been developed. A C-S bond and C-N bond are simultaneously constructed in only one step. The reaction under simple mild conditions features a broad substrate scope, atom economy, high yields (up to 94%), and excellent functional group tolerance.

An efficient synthesis of diarylalkynes was achieved from the domino cross-coupling reaction of 1,1-dichloroalkenes with triarylbismuth reagents under palladium-catalyzed conditions. Under the established palladium protocol, 1,1-dichloroalkenes demonstrated hitherto unknown remarkable cross-coupling reactivity with organometallic triarylbismuth reagents to furnish functionalized diarylalkynes.

The invention discloses an acetyenic-ketone-promoted CuI-catalyzed method for conducting a Sonogashira coupled reaction. The method includes the steps that acetyenic ketone rich in pi-sigma electrons serves as a ligand, CuI serves as a catalyst, a Sonogashira cross coupling reaction between aryl halide and terminal alkyne is catalyzed, and arylethynylene compounds are synthesized. The method is simple in operation and mild in condition, a substrate is good in applicability, a toxic phosphine ligand is avoided, CuI consumption is obviously reduced, and the method can be widely applied to synthesis of the arylethynylene compounds.
