Dienes readily undergo Diels–Alder reaction with CH2C(NO2)SO2Ph (2a), CH2C(NO2)CO2Et (2b), and CH2C(NO2)COPh (2c), all observed in situ by 1H NMR. The cycloadducts of 2a undergo SRN1 reactions.
二烯容易与CH Diels-Alder反应2 C(NO 2)SO 2 Ph(上图2a),CH 2 C(NO 2)CO 2的Et(图2b),和CH 2 C(NO 2)COPH(2C),所有都通过1 H NMR原位观察。2a的环加合物经历S RN 1反应。
