Bimacrocyclic和无环米-terphenylsulfinic酸5,7和9已被合成。已经在2-甲氧基乙醇/水(80:20 w / w)中测量了酸度,并将其与类似的苯甲酸的酸度进行了比较。四-邻的外芳基环的3'-取代米-三联苯-2'-酸导致在酸度降低,其可能是由相应的阴离子的溶剂化受阻而引起的。
2'-position have been used in general protonations leading to reagent-controlled selectivity enhancements: up to 96:4 for the gamma/alpha-protonation of unsymmetrically substituted allyl anions, up to 97:3 for the protonation of cyclohexylanions generating preferentially the thermodynamically less stable cis-products. In order to allow a general, reagent-controlled protonation the acidity of the protonating
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
