The reactions of 1,1′‐bis[Li(trimethylsilyl)amino]ferrocene ( 2a ) with selenium‐ or tellurium tetrahalides gave the 1,1′,3,3′‐tetrakis(trimethylsilyl)‐1,1′,3,3′‐tetraaza‐2‐selene‐ and 2‐tellura‐2,2′‐spirobi[3]ferrocenophanes 5 and 6 , respectively. The analogous reaction with tin dichloride afforded the corresponding 2‐stanna‐2,2′‐spirobi[3]ferrocenophane ( 9 ) rather than the expected stannylene 8 . The reaction of 2,2‐dichloro‐1,3‐bis(trimethylsilyl)‐1,3,2‐diazastanna‐[3]ferrocenophane ( 10 ) with the dilithio reagent 2b also gave the spirotin compound 9 , of which the molecular structure was determined by X‐ray analysis. The formation of the products and their solution‐state structures was deduced from multinuclear magnetic resonance spectroscopic studies ( 1 H, 13 C, 15 N, 29 Si, 77 Se, 125 Te, 119 Sn NMR spectroscopy).
