Toluenesulfonyl chloride polymer-supported

Polymer-supported Reagents. Polymer-supported toluene-sulfonyl azide I3I was prepared by reaction of a macroreticular p-toluenesulfonyl chloride resin (prepared, in turn, by chlorosul-fonation of Amberlite XE 305) with excess sodium azide. Resin 13, a solid-phase equivalent of />-toluenesulfonyl azide, can be used for diazo transfer to /3-dicarbonyl compounds (eq 14). Unlike tosyl azide, resin 13 does not detonate on shock treatment and is stable at room temperature. Recently, an analogous benzenesul-fonyl azide resin has been prepared from PS-TsCl. ... [Pg.547]
