摘要
Bimacrocyclic and acyclic m-terphenylsulfinic acids 5, 7 and 9 have been synthesized. Acidities have been measured in 2-methoxyethanol/water (80:20 w/w) and have been compared to the acidities of analogous benzoic acids. Tetra-ortho-substitution of the outer aryl rings of a m-terphenyl-2'-acid leads to a decrease in acidity which is probably caused by hindered solvation of the corresponding anions.
