Silica sulfuric acid (SSA) was firstly used as an efficient catalyst to promote the synthesis of rctt configurational
calix[4]resorcinarenes via one-pot condensation between resorcinol and aromatic aldehydes. The structure of 4-
cyanophenyl-calix[4]resorcinarene (3b) has been determined by single crystal X-ray diffraction.
二氧化硅硫酸(SSA)首次作为一种高效催化剂,通过间苯二酚与芳香醛的一锅缩合,促进了rctt构型钙并[4]间苯二酚的合成。4- cyanophenyl-calix[4]resorcinarene (3b) 的结构已通过单晶 X 射线衍射确定。
