用H_2O_2氧化二芳基二碲酸(8-Me_2NC10H_6Te)_6O8(OH)_2(4)或二芳基二碲酸(8-Me_2NC10H_6Te)_2(7)得到二芳基二碲酸[8-Me_2NC10H_6Te(O)(OH)_2]2(O)(6)，它是这类化合物的第二个成员，也是第一个含有分子内配位取代基的成员。尝试从甲醇重结晶6得到了部分酯[8-Me2NC10H6Te(O)(OH)(OMe)]2(O)(8)。此外，用密度泛函理论计算比较了已知的二芳基碲酸的结构基序。
The oxidation of the telluroxane cluster (8-Me2NC10H6Te)6O8(OH)2 (4) or the diaryl ditelluride (8-Me2NC10H6Te)2 (7) using H2O2 provided the diarylditelluronic acid [8-Me2NC10H6Te(O)(OH)2]2(O) (6), which is the second member of this compound class and the first one to contain an intramolecularly coordinated substituent. Attempts at recrystallizing 6 from Methanol provided the partial ester [8-Me2NC10H6Te(O)(OH)(OMe)]2(O) (8). In addition structural motifs of known diaryltelluronic acids were compared using DFT calculations.
