Abstract
The homocycles (RBi)n (n = 3–5) react with MeC5 H4Mn(CO)2(thf) (thf = tetrahydrofuran) or Fe2(CO)9 to give Bi2[Mn(CO)2MeC5 H4]3 (1) or Bi2Fe3(CO)9 (3). Reaction of R4Bi2 (R = Me3SiCH2) with Fe2(CO)9 in toluene gives R2Bi2Fe2(CO)8 (4) and R4Bi2Fe(CO)4 (5). The heterocycles (RBiS)2(R = 2-(Me2NCH2)C6 H4 (6), 2, 6-(Me2NCH2)2 C6 H4 (7) are formed by reaction of the corresponding dihalides RBiCl2 with Na2S. The reaction of (RBiS)2(R = 2-(Me2NCH2)C6 H4) with W(CO)5(thf) leads to (RBiS)2[W(CO)5]2 (8).
