Ag-TiO2/clay composite photocatalyst for the oxidation-cyclization of 1,2-diamine compounds with propylene glycol or alcohols

Silver-loaded TiO2 (Ag-TiO2) and acidic clay (K10 montmorillonite) composite photocatalyst has been successfully applied for the light-induced conversion of o-phenylenediamine (OPD) and its derivatives to substituted benzimidazoles with various alcohols in acetonitrile using UV-A and solar light. The influence of the various photocatalysts, solvents, and substituents on the yield and selectivity of the products has been investigated. The mechanism of photocatalysis is proposed. Loading silver on TiO2 enhances product yield and selectivity both in UV and solar light. In the presence of primary alcohols, 2-aminothiophenol forms only disulfide and hence Ag-TiO2/ clay can be used as a green catalyst for the synthesis of disulfides.

THERMAL REACTIONS OF 1-ARYL-5-METHYLTETRAZOLES

The mechanism of the thermal reactions of 1-aryl-5-methyltetrazoles, which involve isomerization to the azide, elimination of a nitrogen molecule, and formation of singlet nitrenes followed by isomerization to benzimidazoles and carbodiimides, has been studied by combinig the methods of derivatography and the current arsenal of mass-spectrometric techniques.The influence of the electronic properties of the substituent (in the para position of the benzene ring) on the course of the thermolysis has been established.
