considerable decreasing of the first electron transition and hence is manifested as the bathochromicshift of both absorption and fluorescence spectra; however, the nature of transition does not change. It is established that the considerable changes of the bond lengths in polymethine chain for both vinylogs in the excited state cause firstly the appearance of the fast component in short wavelengths spectral region;
4-Cyanothiazoles are prepared by reacting .beta.,.beta.-dichloro-.alpha.-amino-acrylonitrile with a thioformamide in the presence of an acidic catalyst.
4-氰基噻唑是通过在酸性催化剂存在下将β,β-二氯-α-氨基丙烯腈与硫代甲酰胺反应制备的。

An approach for the synthesis of new 5-amino-4-cyanoxazoles with carboxylate group at the C-2 position, connected to the heterocycle directly or through an aliphatic linker, was developed. This process features readily available starting materials, simple operations, and good to high yields. Wide synthetic applicability of the obtained compounds was also successfully demonstrated by further modifications
Dichloroacetonitrile reacts with HCN to give the title compound, an enamine, acylation of which, followed by treatment with amines, provides a new synthesis of oxazoles.
