Abstract
Überraschend gut zugänglich ist der goldgelbe Ni‐Komplex 1 des unsubstituierten 1,2,4,5‐Tetradehydrobenzols C6H2. In nur vier Stufen kann 1 aus [NiCl2(PPh3)2] und 1,2‐Dichlor‐4‐fluorbenzol synthetisiert werden. Die C6H2Ni2‐Einheit ist planar, und im C6H2‐Ring sind die Winkel teilweise deformiert (Cy = Cyclohexyl). magnified imageKeywords
