Visible light mediated copper catalysed denitrogenative oxidative coupling of 2-hydrazinopyridines with terminal alkynes to form 2-(alkyl/arylethynyl) pyridines in the presence of O2 at room temperature is reported with 42 examples. This is the first report on visible light stimulated N2 elimination by an in situ generated copper(II) superoxo/peroxo complex. N2 and water are the only by-products. The

A series of compounds based on the mGluR5‐selective ligand 2‐methyl‐6‐(phenylethynyl)pyridine (MPEP) were designed and synthesized. The compounds were found to be either structural analogues of MPEP, substituted monomers, or dimeric analogues. All compounds retained mGluR5 selectivity with only weak or no activity at other mGluRs or iGluRs. The substituted analogue, 1,3‐bis(pyridin‐2‐ylethynyl)benzene

The reactions of Ru3(CO)12 in a refluxing acetonitrile-toluene solution with a half equivalent of the ligand 1,3-bis(pyridin-2-ylethynyl)benzene afforded Ru3(CO)7(μ-CO)[μ-(2-PyCCH)(1,3-C6H3)(2-PyCC)]Ru4(CO)12 (compound 1) and Ru3(CO)7(μ-CO)[μ-(2-PyCCH)(1,3-C6H2)(2-PyCCH)]Ru3(CO)8 (compound 2). Separately, Ru3(CO)12 was treated with a half equivalent of 1,4-bis(pyridin-2-ylethynyl)benzene in a refluxing
receptor 5 (mGlu5) with partial allosteric antagonists has received increased interest due to their favourable in vivo activity profiles compared to the unfavourable side-effects of full inverse agonists. Here we report on a series of bispyridine benzene derivatives with a functional molecular switch affecting antagonistic efficacy, shifting from inverse agonism to partial antagonism with only a single
