Synthesis of 1,3-Di(2-thiazolyl)azulene and Its Selective Chromogenic Response to Mercury(II) Ion

Abstract

Pyrroles prepared by the reaction of alkyl isocyanoacetates with nitroalkenes or vinylsulfones (Barton-Zard reaction, BZ reaction) are useful for the synthesis of biologically active pyrroles, porphyrins, polypyrroles, and dipyrromethene dyes.This review covers recent development of the BZ reaction and its application to the field of material science.CNCH 2 CO 2 R base + 1,5-H shift
