General Cu-Catalyzed Csp-S Coupling

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.

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

Phosphine-substituted 1,2,3-triazoles as P,C- And P,N-ligands for photoluminescent coinage metal complexes

A series of homo- and hetero-polynuclear coinage metal complexes based on a phosphine-substituted 1,2,3-triazole system is presented. Besides the P,N-ligand 1-benzyl-4-(diphenylphosphanyl)-1H-1,2,3-triazole (LPN), the P,C-donor ligand 1-benzyl-
