Partially Oxidised Products of Magnus Green Salt and Similar Conducting Solids
In the recent years a number of papers have been published concerning the partially oxidised product of Magnus green salt (MGSPOP) [1-4]. The crystallographic data are not in agreement with the spectroscopic results. The reason of this disagreement is that two compounds in different proportion are formed during the oxidation [5]. In this paper we describe the isolation and characterization of t...
متن کاملZwitterionic imidazolium salt of [MOEI]-BSA: An efficient solid acid catalyst-promoted green synthesis of quinoxaline derivatives
Easily synthesized1-methyl-3-(2-oxyethyl)-1H-imidazol-3-ium-borate sulfonic acid {[MOEI]-BSA} as a novel catalyst efficiently promoted the synthesis of quinoxaline derivatives via condensation of various diamines with 1,2-dicarbonyl compounds at room temperature conditions in ethanol. This research provides a new method for the synthesis of quinoxalines in good to excellent yields with little c...

متن کاملApplication of Green Chemistry in the Synthesis of Thiopyran Derivatives
An efficient synthesis of 2H-thiopyran derivatives via three-component reaction of alkyl propiolate, benzoyl isothiocyanate or its derivatives and alkyl bromides in the presence of triphenylphosphine in water at 80o C without using any catalyst in water is described. The method offers several advantages including high yields of products and an easy work-up procedure.
