The direct coupling reactions of 1,8-naphthalimide compounds efficiently occurred at 130 or 170 degrees C without the intervention of the leuco form dyes in the presence of base complex reagent, t-BuOK/1,5-diazabicyclo[4.3.0]non-5-ene (DBN), to give the corresponding perylene dyes in good yields with > 95% purities. A possible mechanistic speculation for these oxidative coupling reactions is briefly

synthesis of more difficult aniline-derived PDIs. Furthermore, an automated continuous TSE process for Pigments Black 31 and 32 is demonstrated, with a throughput rate of about 1500 g day-1 , corresponding to a space time yield of about 30×103 kg m-3 day-1 , which is 1-2 orders of magnitude greater than for solvent-based batch methods. These methods provide substantial waste reductions and improved
报道了一种使用双螺杆挤出(TSE)合成各种萘酰亚胺和di二酰亚胺(PDI)的连续,可扩展且无溶剂的方法。使用TSE,无需过量的胺反应物或产物纯化即可定量获得萘酰亚胺。具有良好的官能团耐受性,以50-99%的产率获得了烷基和苄胺衍生的PDI(包括商业染料)。使用K2 CO3可以合成更困难的苯胺衍生PDI。此外,展示了用于颜料黑31和32的自动化连续TSE工艺,其吞吐速率约为1500 g day-1,对应于约30×103 kg m-3 day-1的时空产量,即1比基于溶剂的批处理方法大-2个数量级。
