摘要:
AbstractMetathesis reactions employing lead fluorothiolates and C6H4‐1,3‐(CH2Br)2 afford the corresponding pincer‐type dithioether ligands C6H4‐1,3‐(CH2SRf)2 [Rf = C6H4F‐2 (L1), C6H4F‐3 (L2), C6H4F‐4 (L3), C6H4CF3‐2 (L4), C6H4CF3‐3 (L5), and C6H4CF3‐4 (L6)]. A series of PdII pincer‐type complexes [PdCl(κ3‐Ln)], 1 to 6, were prepared and fully characterized. The X‐ray diffraction molecular structures of C6H4‐1,3‐[CH2S(C6H4F‐4)]2 (L3), [PdCl(SCS–C6H4F‐2)] (1), [PdCl(SCS–C6H4F‐3)] (2), [PdCl(SCS–C6H4F‐4)] (3), [PdCl{SCS–C6H4(CF3)‐2}] (4), and [PdCl{SCS–C6H4(CF3)‐4}] (6) are also reported.
