We developed a regiodivergent syntheses of 4- and 5-bromo-substituted 1,2,3-triazoles in copper-catalyzed azide-alkyne cycloadditions (CuAACs) by taking advantage of bromo(phosphoryl)ethyne 1 as a bromoethyne equivalent. A one-shot dephosphorylative CuAAC

Copper-catalyzed cross-coupling of thiols and bromoalkynes affords a mild, rapid, and selective Csp-S coupling with broad scope, enabling the use of aryl-, alkyl-, and silyl-substituted alkynyl coupling partners (38 total examples, 50-99percent yields). Importantly, the method enables the preparation of difficult-to-access bis-heteroatom-functionalized (S,S-, S,P-, and S,N-) alkynes.

A facile and versatile synthesis of ynamines via C(sp)-N bond formation was established. We installed an electron-withdrawing phosphoryl group onto the ynamines to isolate them by column chromatography. Phosphoryl ynamines were synthesized by treatment of

The title compounds form Diels-Alder cycloadducts with a number of dienes, which can be transformed into vic-bromo(trimethylstannyl)olefins, ultimate precursors for the synthesis of benzocyclotrimers via copper-mediated cyclotrimerization. The overall res
