Se. Kabir et al., SYNTHESIS, STRUCTURE, AND REACTIVITY OF ELECTRON-DEFICIENT COMPLEXES OF QUINOLINES WITH TRIOSMIUM CLUSTERS, Organometallics, 14(8), 1995, pp. 3611-3613
The reaction of Os-3(CO)(10)(CH3CN)(2) with quinolines at 25 degrees C
affords the series of complexes (mu-H)(mu-n(2)-C9H4(R)R'N)Os-3(CO)(10
) (R = H, R' = H (1a); R = 4-CH3, R' = H (1b), R = H, R' = 6-CH3 (1c))
. These complexes are thermally decarbonylated to give the 46e(-) clus
ters (mu-H)(mu(3)-eta(2)-C9H4(R)R'N)Os-3(CO)(9) (R = H, R' = H (2a); R
= 4-CH3, R' = H (2b); R = H, R' = 6-CH3 (2c)). The reactivity of thes
e novel electron-deficient clusters is reported.
