Popis:	The synthesis of complexes 2 [W(CC 6 H 4 (CCC 6 H 4 NH 2 -4)-4)Cl(CO) 2 (dppe)], and 4 [W(CC 6 H 4 (CCC 6 H 4 (CCC 6 H 2 i Pr 2 -3,5-NHCHO-4)-4)-4)Cl(CO) 2 (dppe)], was achieved by Pd(II) catalyzed cross-coupling reactions of complex 1 [W(CC 6 H 4 I-4)Cl(CO) 2 (dppe)], with the respective aromatic acetylenes. Formylation of complex 2 with acetic formic anhydride affords the formamide 3 [W(CC 6 H 4 (CCC 6 H 4 NHCHO-4)-4)Cl(CO) 2 (dppe)]. The isocyanide derivatives 5 [W(CC 6 H 4 (CCC 6 H 4 NC-4)-4)Cl(CO) 2 (dppe)], and 6 [W(CC 6 H 4 (CCC 6 H 4 (CCC 6 H 2 i Pr 2 -3,5-NC-4)-4)-4)Cl(CO) 2 (dppe)], were obtained by dehydration of complexes 3 and 4 with triphosgene/NEt 3 .
