 Title    Rutheniumkomplexe mit Diazadienen, VI [1] f/ 6 -Cycloheptatrien-und ?7 4 -Norbornadien-diazadien-ruthenium(0)-Komplexe Ruthenium Complexes with Diazadienes, VI [1] ^ 6 -Cycloheptatriene-and >; 4 -Norbornadiene-diazadiene-ruthenium(0) Complexes  
 Abstract    Reduction of [(cyclo-C 7 H 8)RuCl 2 ]2 in the presence of a diazadiene RN-CH—CH=NR (DAD; R = 2-C3H7) gives red, airsensitive, sublimable ()/ 6 -C 7 H 8)Ru(DAD) (5). A rigid structure on the basis of the 'H NMR spectrum is excluded. On the other hand pentacoordinate complexes [(j/ 4 -ttor-C 7 H 8)Ru(DAD)P(C 6 H 5) 3 ] (8) or [(^ 4 -«or-C 7 H 8)Ru(DAD)CO] (9) have rigid, C s -sym-metric, square-pyramidal structures. They are obtained by chemical or irreversible electro-chemical reduction of [(>7 4 -rcor-C 7 H 8)Ru(DAD)Cl 2 ] to [(^ 4 -nor-C 7 H 8)Ru(DAD)(solv)] (7) (solv = tetrahydrofuran or acetonitrile) and addition of phosphine or carbon monoxide. 7, in non-coor-dinating solvents, is a stereospecific catalyst for the 1-alkene —trans-2,.. ,-alkene isomerization.
