The Formation of Heterocyclic Compounds from Carbon Disulfide

Abstract

Carbon disulfide has been readily available since the earliest days of organic chemistry and has proved to be a versatile building block for construction of a wide variety of heterocyclic compounds. In this review we have aimed to present the most important examples of reactions in which a heterocycle is formed either from CS₂ or from a readily formed adduct such as a xanthate, dithiocarbamate, trithiocarbonate or trialkylphosphine adduct. The material is ordered so that the heterocyclic products appear in order of: (i) increasing ring size, (ii) increasing number of heteroatoms and, (iii) decreasing priority of heteroatoms.

Key Words:

• Carbon disulfide
• heterocycles
• synthesis
