Abstract
An efficient reductive amination of aldehydes and ketones in the preparation of aliphatic and aromatic secondary and tertiary amines with xylylene ionene borohydride as a high capacity polymer supported reducing agent in isopropanol at reflux under neutral conditions is described. Xylylene ionene borohydride is easily prepared by mixing an aqueous solution of xylylene ionene chloride with an alkaline solution of sodium borohydride at room temperature. The chemoselective reductive amination in the presence of functional groups such as chloride, C=C bond, nitro and cyano groups was also achieved. The generality of reaction was established using variety of aldehydes, ketones and amines.
Keywords: Ionene borohydride, reductive amination, aldehyde, ketone
