Abstract

The synthesis of complexes 2 [W(CC₆H₄(CCC₆H₄NH ₂-4)-4)Cl(CO)₂(dppe)], and 4 [W(CC₆H₄(CCC₆H₄(CCC ₆H₂iPr₂-3,5-NHCHO-4)-4)-4)Cl(CO) ₂(dppe)], was achieved by Pd(II) catalyzed cross-coupling reactions of complex 1 [W(CC₆H₄I-4)Cl(CO)₂(dppe)], with the respective aromatic acetylenes. Formylation of complex 2 with acetic formic anhydride affords the formamide 3 [W(CC₆H₄(CCC₆H ₄NHCHO-4)-4)Cl(CO)₂(dppe)]. The isocyanide derivatives 5 [W(CC₆H₄(CCC₆H₄NC-4)-4)Cl(CO) ₂(dppe)], and 6 [W(CC₆H₄(CCC₆H₄(CCC ₆H₂iPr₂-3,5-NC-4)-4)-4)Cl(CO) ₂(dppe)], were obtained by dehydration of complexes 3 and 4 with triphosgene/NEt₃.
