4,6), and Ph4BiOC6H2(Cl3-2,4,6). Tetraphenylbismuth aroxides are produced by the disproportionation reaction of ligands from pentaphenylbismuth and triphenylbismuth diaroxides in toluene or from pentaphenylbismuth and phenol. Triphenylbismuth diaroxides are synthesized from phenol, triphenylbismuth, and hydrogen peroxide taken at a molar ratio of 2 : 1 : 1, respectively, in diethyl ether. According
合成了五价铋的四个新的配合物:Ph 3 Bi [OC 6 H 2(Br 3 -2,4,6)] 2,Ph 3 Bi [OC 6 H 2(Cl 3 -2,4,6)] 2,Ph 4 BiOC 6 H 2(Br 3 -2,4,6 )和Ph 4 BiOC 6 H 2(Cl 3-2,4,6)。通过配体从甲苯中的五苯基铋和三芳基二氧化物的歧化反应或甲苯中的五苯基铋和苯酚的歧化反应,可以制得四苯基铋的氧化物。三苯基三氧化二铋是由苯酚,三苯基铋和过氧化氢分别在乙醚中以2:1:1的摩尔比合成的。根据X射线衍射数据,包围在2,4,6-三溴苯氧基四苯基铋中的铋原子具有在轴向位置带有烷基的配体的三角形双锥体的构型。Bi-C和Bi-O键的长度分别为2,184、2.190、2.234和2.514Å,赤道CSbC角等于111.4°,121.3°和121.3°。
