水介质中合成5-芳亚叉基罗丹宁

Synthesis of 5-(Arylmethylene) Rhodanines in Aqueous Media

报道了一种合成5 芳亚叉基罗丹宁的新方法.由芳香醛与罗丹宁在碳酸钾水溶液中,于十六烷基三甲基溴化铵(CTMAB)存在下,室温搅拌生成.此方法具有反应简便、收率高、成本低的特点,是对环境无害的合成方法.

A new synthesis procedure of 5-(arylmethylene) rhodanines from aromatic aldehydes and rhodanine in K_2CO_3 water solution at room temperature and in the presence of Hexadecyltrimethylammonium bromide (CTMAB) is reported. This is a simple, efficient, high yielding, economical and environmental-harmless method.
