The hydrolysis kinetics of N-cyanoazoles in alkaline solutions is described by a first-order kinetic equation with respect to the substrate and concentration of hydroxide ions. The hydrolysis rate constants increase with increasing number of nitrogen atoms in the heterocyclic moiety and decrease with introduction of the annelated benzene ring.

Methoxy isothiocyanate has been identified as a product of pyrolysis of the silver salt of N-methoxydithiocarbamic acid. It is also formed on FVT of 1-(N-methoxythiocarbamoyl)imidazole and 1-(N-methoxythiocarbamoyl)-1,2,4-triazole. Methoxy isothiocyanate was identified by IR spectroscopy in argon matrices at 10 K supported by good agreement with the ab initio and DFT calculated spectrum. Isopropoxy isothiocyanate was generated from the corresponding silver salt in a similar manner. The oligomerization of MeONCS to trithiolanes and tetrathianes is also described.

We report the syntheses of ribonucleoside 5′-monophosphates activated with imidazole, using a mechanism which relies on the in situ generation of cyanogenchloride from the reaction of cyanide anion with hypochlorous acid. Cyanogenchloride reacts rapidly with imidazole to form diimidazole imine as the major product, a species which affords the activation of ribonucleoside 5′-monophosphates to their

arenes and heteroarenes into the ortho-cyano derivatives was achieved through directed lithiation followed by electrophiliccyanation with phenyl cyanate. This reaction method proved to be applicable to halogen–lithium exchanged intermediates, so especially useful for the synthesis of benzonitriles. The scope of the reaction sequence was explored using a number of substrates.
