“…The two equatorial W-C bonds (1.966(4) and 1.971(3) Å) are somewhat shorter than their axial counterparts (2.028(3) and 2.034(3) Å). The W-S bonds in the complex 4 (2.5388(8) and 2.5460(8) Å) are close to those found in (CO) 4 W(1,2-(MeS) 2 C 6 H 4 -κ 2 -S(1),S(2)), 15 (CO) 4 W-[(MeSC 5 H 3 ) 2 Fe)-κ 2 -S(1),S(2)], 16 (CO 17 (CO) 4 W[(MeSC 5 H 3 ) 2 Ru)-κ 2 -S(1),S(2)], 18 [(CO) 4 W] 2 -[(C 5 (SMe) 5 )Mn(CO) 3 -κ 4 -S(1),S(2), S(1′),S(2′)], 19 rac-and meso- 20 The two methyls are in a syn relationship and are turned upward relative to the pentagonal face of the carborane ligand in contrast to the structure of ( 5d where both the methyls are turned downward relative to the pentagonal face. The C carb -C carb bond in complex 4 is shorter than in ligand 3, which reflects reduced electron donation from the sulfur atoms to the carborane cage while C(7)-B (11) and C(8)-B(9) are only slightly elongated (Table 1).…”

“…Die Verwendung von Butyllithium als Base erlaubte zwar eine Vielzahl stereo spezifischer Synthesen ausgehend von Dimethylaminomethylferrocen [10] und nahe verwandten Systemen [11] zu di-und trifunktionellen Cyclopentadienyl-Komplexen, schien aber bei Abwesen heit einer Stickstoff-Donorfunktion entweder ganz zu versagen oder zu nicht trennbaren Produktge mischen zu führen [12]. Wir entdeckten vor weni gen Jahren, daß der Halogen-M etall-Austausch an Perhalogencyclopentadienyl-Komplexen unter schonenden Bedingungen die Einführung einer Vielzahl funktioneller G ruppen ermöglicht [13], und daß insbesondere bis zu fünf M ethylthioreste stufenweise und jeweils regioselektiv an den Cyclo pentadienylring gebunden werden können [14,15]. Wir haben jetzt untersucht, ob der von uns beob achtete spezifisch in 3-Stellung dirigierende Effekt …”
