Acid catalysed condensation of resorcinol and pyrogallol with aromatic aldehydes using a microfluidic vortex fluidic device (VFD) under continuous flow conditions results in the selective formation of resorcin[4]arenes and pyrogallol[4]arenes as predominantly their C(4v) isomers. Notably C(2v) isomers and C(2h) isomers can be also prepared with the latter being converted to the C(4v) isomer when the VFD operates in confined mode.
在连续流动条件下，使用微流控涡旋流设备（VFD）催化间苯二酚和焦儿茶酚与芳香醛的酸催化缩合反应，选择性地生成间苯[4]芳烃和焦儿茶[4]芳烃，主要为它们的 C(4v)异构体。值得注意的是，也可以制备 C(2v)异构体和 C(2h)异构体，当 VFD 以受限模式运行时，后者可以转化为 C(4v)异构体。
