手性苯并咪唑铜(Ⅱ)络合物催化合成1,1''''-联-2萘酚

In the past several decades, much attention has been paid to optically active, C2-asymmetric 1,1′-binaphthalene-2,2′-diol and its derivatives because of their application in inducing chirality in asymmetric synthesis[1,2]. Enantiomerically pure 1,1′-binaphthalene-2,2′-diol has been prepared by many methods ranging from the classical resolution via crystallization of the diastereoisomeric salts[3] to asymmetric oxidative coupling[4～6].

二(桥-氯)-二[氯-(N，N，N′-三苄基乙二胺)铜(Ⅱ)]的晶体结构(英)

The crystal structure of the title complex, [Cu(C₂₃H₂₆N₂)Cl₂]₂·2CH₂Cl₂, has been determined by single-crystal, X-ray diffraction techniques. The compound crystallizes as dark-green prisms in space group P2₁/c of the monoclinic system, with Z=4 and unit cell dimensions a=1.710 9(7) nm, b=2.395 2(11) nm, c=1.348 9(6) nm and β=110.651(8)°. The complex consists of two similar but crystallographically independent dimers, of which Cu(Ⅱ) centers display five-coordinated trigonal-bipyramidal geometry with Cu-Cu separations in two centrosymmetric dimers are 0.345 1 and 0.347 8 nm, respectively, and in each dimer the two copper centers share a common edge formed by two bridging chloride ions, each being equatorial. Solvent molecules of CH₂Cl₂ are packed together in the crystal lattice. CCDC: 253299.
