N-Substituted phthalimides can be obtained in very good yields, under essentially neutral conditions, by mixing or heating an alkyl (oraryl) azide, triphenylphosphine, and phthalic anhydride in benzene or toluene, in the presence of a catalytic amount of tetrabutylannionium cyanide. Application of the reaction into the domain of carbohydrates is promising.
N-取代的邻苯二甲酰亚胺可以在基本中性的条件下,通过在催化量的氰化四丁基亚铵存在下,将烷基(或芳基)叠氮化物,三苯基膦和邻苯二甲酸酐在苯或甲苯中混合或加热,以非常高的收率获得。该反应在碳水化合物领域的应用是有前途的。
