Koordinaation von Diazoverbindungen an Cobalt(I)-Zentren Struktur von Methyl(Diazocyclopentadien) tris(Trimethylphosphan) cobalt

Co(cyclo-C 5 H 8 )(PMe 3 ) 3 is oxidized by diazocyclopentadiene to give Co 2 (N 2 C 5 H 4 )(PMe 3 ) 5 . Cobalt (I) compounds CoRL'L 3 (R=CH 3 , 4-CH 3 C 6 H 4 , COCH 3 ; L'=PMe 3 , CO; L=PMe 3 ; 3L=CH 3 C(CH 2 PMe 2 ) 3 ) or CoRL 3 (R=Cl, C 6 F 5 ; L=PMe 3 ) accommodate diazoalkane ligands to give 18 electron complexes CoR(N 2 R')L 3
