Abstract
The synthesis, characterization and reactivity of bipyridyl ruthenium carbonyl complexes of the type Ru(NN)(CO)
2Cl
2 [where NN = 4,4′-
tBu
2-2,2′-byy (bpy
∗,
a); 6,6′-Me
2-4,4′-
tBu
2-2,2′-bpy (dmbpy
∗,
b); 6,6′-Ph
2-4,4′-
tBu
2-2,2′-bpy (dpbpy
∗,
c)] is reported together with the synthesis and characterization of Ru(dpphen)(CO)
2Cl
2 [where dpphen = 2,9-Ph
2-1, 10-phen,
d]. When NN is bpy
∗ or dmbpy
∗, the
cis-carbonyl,
trans-chloro isomer is obtained, whereas when NN is dpbpy
∗ or dpphen the
cis-carbonyl,
cis-chloro isomer is the predominant product.
