Copper dinuclear complexes

In their pursuit of determining solution structures of dinuclear copper complexes as carried out for complex (29) (Section 6.6.3.1.1). Comba reported complex (431) (r = 0.02 Cu-Cu 6.9 A, comparable with the values of 7.2 A predicted by molecular mechanics calculations and 6.7 A obtained from the simulated EPR spectrum).54 They reported369 complexes (432) (square planar) and (433) (Cu-Cu 3.35 A) as well. As part of studying magnetic properties of mono-, di-, and... 

The subject molecules are obtained as dinuclear copper complexes with the octa-aza cryptate ligands L1 and L2 shown in Scheme 1. 

Cai et al. (71) examined the use of dinuclear copper complexes as catalysts in the cyclopropanation reaction. Their ligand design, based on the success exhibited by the Aratani system, incorporates a diimine aryloxide. A comparison of the mononuclear catalyst 99 with the corresponding dinuclear catalyst 100 showed certain modest benefits conferred by the latter, Eq. 52. The authors note that these catalysts are effective at ambient temperature but isolated yields are higher at 50°C with no loss in enantioselectivity.

Tanaka reported the synthesis of (/ )-muscone (10) by an enantioselective conjugate addition of chiral alkoxydimethylcuprate, which was prepared from chiral ercdo-3-[(l-methylpyrrol-2-yl)methylamino]-l,7,7-trimethylbicyclo[2.2.1]heptan-2-ol (9), methyllithium, and copper iodide (Scheme 9.7) [16]. In this reaction, convex deviation from a linear correlation was observed when the chiral ligand had a higher enantiopurity. This positive NLE was probably induced by the formation of a reactive homochiral dinuclear copper complex to give (R)-muscone. Rossitter also observed asymmetric amplification in a copper-catalyzed conjugate addition of methyl-...
