Background: SnCl2.2H(2)O has been used as a convenient precatalyst for the one-pot and rapid synthesis of 2-substituted quinolines under ultrasound irradiation in water. The reaction involved a 3-component reaction of aniline, aldehydes, and ethyl 3,3-diethoxypropionate in the presence of ...
Inexpensive and commercially available SnCl2·2H2O has been shown to be an alternative to Lewis acidic ionic liquids by carrying out a variety of organic synthesis. The reaction medium is recycleable and the reaction time is comparable with the microwave reactions. DOI: 10.1246/cl.2006.632 年份:...
