Koordinationschemie perhalogenierter Cyclopentadiene und Alkine, X [1] Darstellung und Molekülstruktur eines Cyclopentadienyl‐1,3‐dithiol‐π‐Komplexes, [C 5 Cl 3 (SH) 2 ]Mn(CO) 3

Coordination Chemistry of Perhalogenated Cyclopentadienes and Alkynes, X [1] . – Synthesis and Molecular Structure of a Cyclopentadienyl‐1,3‐dithiol π Complex, [C 5 Cl 3 (SH) 2 ]Mn(CO) 3 The reaction of [C 5 Cl 4 Li]Mn(CO) 3 with elemental sulfur leads to [C 5 Cl 4 SLi]Mn(CO) 3 ( 1 ), which is easily oxidized by air to the disulfide (OC) 3 Mn[C 5 Cl 4 S–SCl 4 C 5 ]Mn(CO) 3 ( 2 ). Addition of one equivalent of BuLi, followed by an excess of S 8 produces the dithiolate [C 5 Cl 3 (SLi) 2 ]Mn(CO) 3 ( 3 ), which yields the dithiol [C 5 Cl 3 (SH) 2 ]Mn(CO) 3 ( 5 ) upon hydrolysis. The molecular structures of 2 and 5 have been determined by X‐ray diffraction.
