The reactions of N-(2,4-dichloro-6-oxo-2,4-cyclohexadien-1-ylidene)-4-nitrobenzamide () with various conjugated dienes have been studied. The heterodiene system of reacts with one of the double bonds of E-1, 3-pentadiene, E,E-2,4-hexadiene, E,E-1,4-diphenyl-1,3-butadiene, E,E-2,4-hexadienal, ethyl sorbate, 1-methoxy-1,3-butadiene, cyclopentadiene, 1,2,3,4-tetra-phenylcyclopentadiene in an inverse electron-demand
研究了N-(2,4-二氯-6-氧代-2,4-环己二-1-基)-4-硝基苯甲酰胺()与各种共轭二烯的反应。的杂二烯体系与E-1、3-戊二烯,E,E-2,4-己二烯,E,E-1,4-二苯基-1,3-丁二烯,E,E-的双键之一反应2,4-己二醛,山梨酸乙酯,1-甲氧基-1,3-丁二烯,环戊二烯,1,2,3,4-四苯基环戊二烯在反电子需求的Diels-Alder反应中生成2,3-衍生物二氢-1,4-苯并恶嗪。与上述二烯相反,在N-酰基酰亚胺基团上加成1,3-丁二烯,得到螺环加合物。
