A series of the extremely crowded triarylpnitogens, tris(2,4,6-triisopropylphenyl)phosphine (1), arsine (2), stibine (3), and bismuthine (4), were synthesized by the reaction of 2,4,6-triisopropylphenylcopper(I) with the corresponding pnictogen trichlorides. Introduction [corrected] of the three bulky aryl groups resulted in the unusual structures and redox properties, which were studied by X-ray crystallography
通过 2,4,6 的反应合成了一系列极其拥挤的三芳基硝基化合物,三(2,4,6-三异丙基苯基)膦(1)、胂(2)、锑(3)和铋(4)。 -三异丙基苯基铜(I)与相应的三氯化物。三个庞大的芳基的引入[校正]导致了不寻常的结构和氧化还原特性,通过 X 射线晶体学和循环伏安法进行了研究。三芳基烟原 1、2 和 3 在烟原原子周围具有极大的键角(1:111.5 度,2:109.2 度,3:106.7 度),不仅 1 和 2,而且锑 3 在极低电位下的循环伏安图(1: 0.16 V, 2: 0.50 V, 3: 0.57 V vs Ag/Ag+),这表明相应的阳离子自由基具有相当大的稳定性。
