Copper Ion Mediated Selective Cleavage of C–S Bond in Ferrocenylthiosemicarbazone Forming Mixed Geometrical [(PPh₃)Cu(μ-S)₂Cu(PPh₃)₂] Having Cu₂S₂ Core: Toward a New Avenue in Copper–Sulfur Chemistry

Abstract

Unprecedented selective cleavage of the carbon-sulfur bond of the ferrocenylthiosemicarbazone moiety has been observed for the first time, resulting in the formation of mixed geometrical binuclear copper complex [(PPh(3))Cu(μ-S)(2)Cu(PPh(3))(2)]. Upon trying direct synthesis of the title complex, an unusual tetranuclear [Cu(4)(μ(3)-Cl)(4)(PPh(3))(4)] cubane resulted.
