Novel functional [4]helicenes have been designed and synthesized, in 54%-72% overall yields, through an operational and simple two-step photochemical approach starting from various p-substituted phenylacetonitriles, and were characterized by NMR (1H, 13C,

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.

The photoamination of l-(2-methyl-l-propenyl)naphthalene (1a) with ammonia in the presence of p-dicyanobenzene (p-DCB) occurred selectively at the alkenyl group but not at the naphthyl group to give l-(2-amino-2-methylpropyl)naphthalene (2a). Similarly, the photoamination of several kinds of alkenylnaphthalenes (1) proceeded selectively at the alkenyl group. The photoamination proceeded via the nucleophilic addition of ammonia to the cation radical of 1 generated by the photoinduced electron transfer to p-DCB to give the aminated radical after deprotonation. Distribution of the positive charge in 1+· and the stabilities of the aminated radicals were calculated by the PM3-UHF method. The stabilities of the aminated radicals agreed with the regioselectivity.
