6′-tetraone (1), viz., radical anion salts of the alkali metals (Li, Na, K) and cobaltocenium cations, chelated mono-o-semiquinone complexes with different metal fragments (Tl, TlMe2, SnPh3, Mn(CO)4, Mn(PPh3)(CO)3), a number of copper(I) complexes with sterically hindered phosphines as well as binuclear heterometallic derivatives of triphenylantimony(V) o-semiquinone-catecholate with the analogous paramagnetic
4,4',7,7'-tetra-tert-butyl-2,2'-bis-1,3-benzodithiol-5,5',6,6'-tetraone (1) 的顺磁性衍生物,即。 , 碱金属 (Li, Na, K) 和茂钴阳离子的自由基阴离子盐,螯合的单邻半醌与不同金属片段 (Tl, TlMe2, SnPh3, Mn(CO)4, Mn(PPh3)(CO) 3),通过ESR光谱研究了许多具有空间位阻膦的铜(I)配合物以及具有类似顺磁中心的三苯基锑(V)邻半醌-儿茶酚酸盐的双核杂金属衍生物。二邻醌 1 与钠汞齐的反应导致形成所有还原形式,包括醌-半醌、二半醌、半醌-儿茶酚酸盐和双胆酸盐。带有未配对电子的自由基阳离子位于四硫富瓦烯 (TTF) 片段上,
