prepared in situ in the presence of 2 equiv of PPh3 and 1 equiv of CX4, and the ring-expanding products (N-substituted pyrrolidin-2-ones) were obtained in good yields. The reaction mechanism was investigated on the basis of oxygen-18 tracer experiment.
我们成功地通过在2当量的PPh 3和1当量的CX 4和扩环产物(N-取代的吡咯烷-2-酮)存在下原位制备的相应的酰亚胺基卤化物活化了环丙基酰胺(单活化的环丙烷)。以高收率获得。在氧18示踪实验的基础上研究了反应机理。
