Abstract

Abstract Tritylation of tetrazole and its 5-substituted derivatives with triphenylmethyl chloride under conditions of phase-transfer catalysis regioselectively yields the corresponding 5- substituted 2-trityltetrazoles which can be used to protect NÄH bonds in nitrogen-containing heterocycles and OÄH bonds in primary alcohols. Thermolysis of 2-trityltetrazoles in benzonitrile leads to 3, 6-disubstituted 1, 2, 4, 5-tetrazines. Thermal transformation of the ...
