Diethyl (iodoethynyl)phosphonate and (iodoethynyl)diphenylphosphane oxide: Crystal structures and some cycloaddition reactions

The title compounds are difunctionalized acetylenic building blocks, which can serve as electrophilic dienophiles and dipolarophiles in [4+2] and azide-iodoalkyne [3+2] cycloaddition reactions, which, however, require strong thermal activation. In their c

Process-Controlled Regiodivergent Copper-Catalyzed Azide-Alkyne Cycloadditions: Tailor-made Syntheses of 4- And 5-Bromotriazoles from Bromo(phosphoryl)ethyne

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

Synthesis of Ph2P(O)-stabilized Ynamines via C(sp)-N bond formation and their dephosphorylative copper-catalyzed click reaction

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
