A carbon nitride material can be combined with homogeneous nickel catalysts for light-mediated cross-couplings of aryl bromides with alcohols under mild conditions. The metal-free heterogeneous semiconductor is fully recyclable and couples a broad range of electron-poor aryl bromides with primary and secondary alcohols as well as water. The application for intramolecular reactions and the synthesis of active pharmaceutical ingredients was demonstrated. The catalytic protocol is applicable for the coupling of aryl iodides with thiols as well.

Rhodium-catalyzed Mizoroki-Heck type reaction of nitriles via the cleavage of C-C bonds is described. Orthogonal and iterative functionalizations of arenes were also demonstrated by combining the present and conventional halide-based cross-coupling reacti

In recent years we have used palladium-catalysed cross-coupling procedures to prepare a large number of very interesting lateral mono- and di-fluoro-substituted terphenyls.Similar methodology has been applied in the synthesis of lateral cyano-substituted terphenyls to assess the extent to which the mesophases of such systems can tolerate the larger cyano group; the synthetic routes to these compounds are discussed in detail.The compounds with the lateral cyano-substituent in the centre ring have very low melting points and liquid crystal phases exhibited (SC, SA and nematic) are dependent on the terminal substituents.The compounds with the cyano-substituent at the edge of the terphenyl core are still quite low melting and they have very wide SA ranges. Keywords: lateral cyano-substitution, 1,1':4',1''-terphenyls, palladium-catalysed cross-coupling
