Pt(ii) phenylbipyridine complexes possessing bis(phenylisoxazolyl)phenylacetylene ligands self-assembled to form stacked aggregates via Pt-Pt, π-π stacking, and dipole-dipole interactions. The assembled structures were influenced by the solvent properties. Non-helical assemblies found in chloroform displayed metal-metal-to-ligand charge transfer absorption and emission, whereas helical assembli...

The donor properties of a set bulky ferrocene based bisphosphanes (Fe(C5H4PMes2)2 and (C5H4PMes2)Fe(C5H4PtBu2 with Mes= mesityl tBu=tert-butyl) were probed by exploring the NMR parameters corresponding selenophosphoranes amended cyclovoltammetry. ligand explored in complexation copper phenylacetylide which is relevant as intermediate Cu(I) catalyzed CO2 addition to phenylacetylene. Owing poor s...

A one pot green three‐component coupling reaction of aldehyde, phenylacetylene, and amine derivatives in the presence of copper (II)–thioamide combination as a novel and efficient heterogeneous catalyst under solvent–free conditions is reported. The catalyst displayed high activity and afforded the corresponding propargylamines in good to high yields. The key to this procedure was the generatio...

A facile and one-pot multicomponent synthesis of novel 1,4-disubstituted-1H-1,2,3-triazoles from alkenes at room temperature is reported. At the first step, in the presence of I2/NaN3 reagents, various alkenes were converted to the corresponding azido iodides and in the next step, the reaction of these compounds with phenylacetylene in the presence of catalytic amount of sodium ascorbate/ CuSO4...

Exposure of a Au(111) surface to ethynylbenzene in solution leads to the formation of a bound monolayer. A chemisorption process occurs to give a stable layer consisting of oxygen-containing hydrocarbon species. Ethynylbenzene itself does not oxidize under the deposition conditions indicating that the gold surface facilitates the oxidation process. Calculations show that ethynylbenzene and its ...

Transition metal-catalyzed hydroalkynylation reactions are efficient transformations allowing the straightforward formation of functionalized alkynes. Therein, we disclose cobalt-catalyzed vinylaziridines giving rise to both linear and branched enynes. The optimization reaction conditions allowed determine key parameters cobalt-based catalytic system. scope investigation showed that is mainly l...

An investigation into species formed following precatalyst activation in Mn-catalyzed C–H bond functionalization reactions is reported. Time-resolved infrared spectroscopy demonstrates that light-induced CO dissociation from precatalysts [Mn(C^N)(CO)4] (C^N = cyclometalated 2-phenylpyridine (1a), 1,1-bis(4-methoxyphenyl)methanimine (1b)) a toluene solution of (2a) or (2b) results the initial fo...
