“…12 Iron selenocarboxylates show antifungal, antibacterial effects and are active substrates against cancer cells. 14,15 In the past two decades, we have developed a synthetic methodology for iron complexes of the general formula CpFe(CO) 2 EQ (E= S, Se, Q= COR, 16,17 SO 2 R, 18,19 COCO 2 R, 20 CO 2 R, 21,22 C(S)OR, 23,24 C(O) SR, 25,26 CS 2 R 27 ). This methodology involves the interaction of iron sulfides or selenide bridged dimers (l-E x )[CpFe(CO) 2 ] 2 (E = S, x = 2-4; E = Se, x = 1) with the corresponding chlorides (QCl).…”
