as‐Triazine chemistry. V.The oxidative ring‐opening of 5,6‐diphenyl‐as‐triazine‐3(2H)‐ones with Organic Peracids

Abstract

The structures of the oxidation products of 5,6‐diphenyl‐as‐triazine‐3(2H)‐ones (Ia‐b) with organic peracids were chemically and spectroscopically reinvestigated and it was concluded that the products were 1,4‐dibenzoyl semicarbazide (IIa) and the 2‐methyl analogue (IIb).
