Description Photolysis of a hexane solution containing ironpentacarbonyl, 1-ferrocenyl-4-phenyl-1,3-butadiyne at low temperature yields six new products: [Fe(CO)(2){eta(2): eta(2)-PhC CCC(Fc)C(C CPh)C(Fc)Fe(CO)(3)}-mu-CO](1), [Fe(2)(CO)(6){mu-eta(1): eta(1): eta(2): eta(2)-PhC CCC(Fc)-C(O)-C(Fc)CC CPh}] (2), [Fe(2)(CO) 6{mu-eta(1): eta(1): eta(2): eta(2)-FcCC (C C Ph)-C(O)-C(Fc)CC CPh}] (3),[Fe(2)(CO)(6){mu-eta(1):eta(1):eta(2):eta(2)-FcC CCC(Fc)-C(O)-C(Fc)CC CPh}] (4), [Fe(CO)(3){mu-eta(2):eta(2)-[FcCC(C CPh)C(C CPh)C(Fc)}CO](5) and [Fe(CO)(3){mu-eta(2): eta(2)-[FcCC(C CPh)C(C CPh) C(Fc)} CO] (6) formed by coupling of acetylenic moieties with CO insertion on metal carbonyl support. In presence of CO, formation of another new product 2,5-bis(ferrocenyl)-3,6-bis(tetracarbonylphenylmaleoyliron) quinone (7) was observed which on further reaction with ferrocenylacetyene gave the quinone, 2,5-bis(ferrocenyl)-3,6-bis(ethynylphenyl) quinone (8). Structures of 1-5 and 8 were established crystallographically. (C) 2010 Elsevier B. V. .
