A new and convenient method for the acid-catalysed Michael addition reactions of alcohols, thiols and amines to methyl vinyl ketone has been developed using the ionic liquid ethyltri-n-butylphosphonium tosylate. The reaction conditions are mild and obviate the need for toxic and expensive Lewis acid catalysts, offering advantages over more commonly used systems.
使用离子液体乙基三正丁基甲苯磺酸phosph,已开发出一种新的便捷的方法,用于醇,硫醇和胺的酸催化迈克尔加成反应生成甲基乙烯基酮。反应条件温和,不需要有毒和昂贵的路易斯酸催化剂,与更常用的系统相比,具有优势。
