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.
