Descripción

General description

2,3-Dimethoxy-1,3-butadiene (DMEBD) is a 1,3-butadiene derivative. The reaction kinetics of hydrolysis of 2,3-dimethoxy-1,3-butadiene in the presence of acid catalyst has been investigated. The [4+2] cycloadditions of 3-nitrocoumarins with DMEBD has been investigated in aqueous medium, in organic solvent and under solventless conditions. This reaction led to the formation of 4-substituted 3-nitrochromanones. It forms adducts with graphene and Diels-Alder chemistry in this formation has been investigated.

Application

2,3-Dimethoxy-1,3-butadiene has been employed as diene to investigate the Diels-Alder chemistry of pristine and defective graphene. It was also used in the synthesis of novel benzopentathiepin varacinium trifluoroacetate.
It may be used in the preparation of 3,4-dimethoxythiophene, an intermediate for the synthesis of 3,4-ethylenedioxythiophene (EDOT). It may also be used to form thio esters by reacting with mercaptans in the presence of cobalt carbonyl catalyst.
