Abstract

A one step synthesis protocol for the conversion of heteroylthiosemicarbazides and 2,3-dichloro-1,4-naphthoquinone to naphtho[2,3-d]thiazoles, naphtho[2,3-e][1,3,4]thiadiazines as well as bis(naphtho[2,3-d]thiazolyl)copper(II) derivatives is described. The products were conclusively confirmed by single crystal X-ray analyses. A mechanism for the formation of the products is presented.
