有机胂化合物的研究——Ⅷ.胂叶立德与叠氮化合物的反应

STUDIES ON ORGANOARSENIC COMPOUNDS——Ⅷ.THE REACTION OF ARSONIUM YLIDES WITH ARYL AZIDES

膦叶立德或硫叶立德与叠氮化合物反应,前者失掉三苯基氧化膦,生成三氮杂茂衍生物;后者失掉二烃基硫,生成苯胺基富马型衍生物和少量三氮烯基富马型衍生物及环丙烷衍生物.胂叶立德与双烯酮的反应,类似于硫叶立德.本文报道胂叶立德与叠氮化合物的反应,进一步探索胂叶立德的一些反应特性.

The reaction of arsonium ylides(1)with aryl azide at room temperature gavethe corresponding olefinic triazenes(2a,b)and enamines(2c～f and 3),respectively.Thus the reaction is similar to that of sulfonium ylides but not of phosphonium ylides.All products have been identified through elemental analyses,IR and 1H NMR.
