Direct C–S Bond Functionalization of Benzyl Mercaptan
Cleavage of a C–S bond of benzyl mercaptan led to formation of a new C–C bond during (Z)-selective alkenylation of nitriles using 1,10-phenanthroline as organocatalyst and tBuOK as a base. Furthermore, we have shown that the cascaded functionalization of benzylic C–S and aryl–halide bonds could be done in one pot. 1H NMR study and kinetic experiments also helped to establish the mechanism of the reaction.

Synthesis, characterisation and photophysical properties of a,a-diaryl-acrylonitrile derivatives
a,b-Diarylacrylonitrile derivatives can be prepared by two different routes: (1) the intermolecular condensation of the same arylacetonitriles (2) the condensation of arylaldehydes and arylacetonitriles with a catalytic amount of NaOCH3 at room temperature. Several a,b-diarylacrylonitrile derivatives have been synthesised in this paper and characterised. The UV-vis absorption and photoluminescent (PL) spectra of the products were investigated.
