Efficient synthesis of thioamide terminated molecular wires

Bis-thioamide terminated 'molecular wires' are formed in a high yield under mild conditions from readily synthesised bis-nitrile terminated molecules and aqueous ammonium sulfide in DMF.

Crystal engineering using very short and linear C(sp)-H···N hydrogen bonds: Formation of head-to-tail straight tapes and their assembly into nonlinear optical polar crystals

The crystallization of 4-ethynylpyridine (1) and 4-(4-ethynylphenyl)ethynylpyridine (2) leads to C(sp)-H···N hydrogen bonded straight tapes that further assemble into polar crystals, in the case of 2, and show intense powder SHG response, 8 times more efficient than crystalline urea.

Selective and efficient access to ortho, meta and para ring-substituted phenylacetylene derivatives R-[C≡C-C6H4](x)-Y (Y:H, NO2, CN, I, NH2)

ortho, meta and para isomers of iodo and amino ring-substituted phenylacetylene as well as rod-like arylacetylene derivatives were prepared by a simple synthetic route involving three consecutive reactions: the palladium-catalysed carbon-carbon bond forma
