Halogen containing complexes

VO(acac)2 < VO(Et-acac)2 VO(Me-acac)2 BMOV. Conversion rates for all hydrolysis products were faster than for the original species. Both EPR and visible spectroscopic studies of solutions prepared for administration to diabetic rats ocumented both a salt effect on the species formed and formation of a new halogen-containing complex. The authors concluded that vanadium compound efficacy with respect to long-term lowering of plasma glucose levels in diabetic rats traced the concentration of the hydrolysis product in the administration solution. 

Scheme 6-30 shows that the halogen-containing complexes RuX2 (BINAP) are excellent catalysts With an S/C of over 103 or even 104, the enantioselective hydrogenation of methyl 3-oxobutanoate can still proceed well in methanol. The yield of the enantioselective reaction is almost 100%.

Interactions between non-halogen-containing IIIB compounds and transition-metal complexes are found in 6.5.3. Most of these IIIB compounds are boron-containing heterocycles. A series of interesting sandwich compounds, including triple- and tetradecked complexes, are synthesized by methods in 6.5.2.1-6.5.3. 

As we were interested in halogen containing nentral complexes further treatment of (6) with KI in acetone at r.t. during 12 h resulted in another complex where the coordinated acetonitrile was substituted by an iodide as shown in Scheme 23.8.

Ruthenium, cobalt and halogen are the key elements of this catalysis (2), although ruthenium in combination with halogen-containing zirconium and titanium derivatives is also effective (3). In the case of the Ru-Oo couple, the highest yields of acetic acid may generally be achieved with ruthenium oxide, carbonyls and complex derivatives in combination with various cobalt halides dispersed in low-melting quaternary phosphonium halide salts (2).
