The synthesis of 2-substituted indoles starting from the corresponding unprotected 2-alkynylanilines was made possible in 3% TPGS-750-M water using Pd(OAc)2 alone as the catalyst. The reaction was sensitive to the heating mode respect to the nature of the starting material as, in many cases, convectional heating was better than microwave dielectric heating. The MW (microwave) delivery mode had also
单独使用Pd(OAc) 2作为催化剂,在3%
TPGS-750-M
水中从相应的未保护的2-炔基
苯胺开始合成2-取代
吲哚成为可能。就起始材料的性质而言,反应对加热模式很敏感,因为在许多情况下,对流加热比微波介电加热更好。 MW(微波)传输模式也会影响副产物的形成,从而影响产品产量。串联 Sonogashira 环化反应也在纳米胶束
水环境中使用 Pd(OAc) 2 /Xphos 完成。
