- Aryl trihydroxyborates: Easily isolated discrete species convenient for direct application in coupling reactions
-
A conceptually and practically simple alternative approach to the use of arylboron species as the organometallic component in cross-coupling processes is described whereby trihydroxyborate salts are isolated and directly employed. The protocol derives practical benefit from the ease and convenience of the isolation and subsequent use of the discrete borate salts, eliminates the need for additional base, and aids the use of correct reaction stoichiometry.

- A green, efficient, and rapid procedure for the hydrogenation of nitroarenes to formanilides in water
-
Abstract: A green, efficient, and rapid procedure for the hydrogenation of nitroarenes to formanilides in Pd(TFA)2/HCOOH system in water is described. Under optimized conditions, the reaction of most substrates is complete within 30?min with yields of 30–93%. Furthermore, this procedure is applied successfully for the modification of natural products, such as arctigenin, vindoline, and estrone. Graphical abstract: [Figure not available: see fulltext.].

- Microwave accelerated synthesis and evaluation of conjugated oligomers based on 2,5-di-thiophene-[1,3,4]thiadiazole
-
A series of π-conjugated 2,5-di-thiophene-[1,3,4]thiadiazole based pentamers have been synthesised by microwave promoted palladium catalysed cross-coupling reactions. The aromatic groups that terminate each pentamer have a profound effect on the observed optical, electrochemical and liquid crystalline properties. Substitution of progressively less electron rich aromatic groups at the periphery of the pentamers decreased the energy gap between the ground state and the first excited state and also lowered the energy of the frontier orbitals sufficiently to impede oxidation and facilitate reduction. The thermotropic calamitic mesogen, 2,5-bis-[5-(4-hexyl-phenyl)- thiophen-2-yl]-[1,3,4]thiadiazole, 7 showed non-dispersive ambipolar charge transport in the nematic, smectic and crystalline phases. The charge mobility increased concomitantly with increasing molecular order of the mesophase to a maximum in the highest ordered smectic phase (hole ≈ 4 × 10-3 cm2 V-1 s-1, electron ≈ 8 × 10-3 cm2 V-1 s-1).
