摘　　要：羟基取代的黄烷酮与NO反应,得到了羟基邻位或对位单硝基化产物.随着反应时间的延长,有羟基邻位和对位双硝基化以及羟基两个邻位双硝基化产物生成.多羟基取代的黄烷酮可以生成多硝基化产物.Hydroxy-substituted flavanones reacted with NO to afford mono- and multi-nitro derivatives. The mononitration occurred at the ortho- or para-position with respect to the hydroxy group. Dinitrations occurred at two ortho-positions or both ortho- and para-positions to the hydroxy group with longer reaction time than mononitration. The reaction of polyhydroxy-substituted flavanones with NO gave polynitrated derivatives.
