PdCl2(camphorquinone dioxime)2,5, 1119 PdC20H32Cl2P 4 [PdCl2(diphos)2]2+. 5,1124 PdC21H17N2PS3... 

Unlike other dioximes, as for example the well-known DMG (Section 50.5.3.7.ii), camphorquinone dioxime, H2CQD, was found to coordinate with O and N atoms in the Ni(HCQD)2 complex which has square planar coordination (345).2504 The reaction of complex (345) with AgN03 in H20/Me0H solution gives a hexanuclear cluster of composition [Ni(HCQD)2Ag]3 (346).2505 Each hexanuclear molecule consists of three Ni(HCQD)2 anions... 

Ligand geometry may alter the coordination properties of dioximes as illustrated by a study of the complexes of camphorquinone dioxime (H2CQD). This ligand exists in four isomeric... 

A series of chiral bis-dioximato complexes of Fe11, Co11, Ni11 and Pd11 have been described from three geometrical isomers ( , j8 and 3) of D-camphorquinone dioxime (Hcqd) and two (fi and <5) of L-nopinoquinone dioxime (Hnqd).41 Opposite Cotton effects around 20000 cm-1 have been observed for Co(a-cqd)2-H20 and Co(<5-nqd)2 H20 indicating their quasi-enantiomeric stereochemistries.. , ... 

Alkoxycarbonylcarbenes, which are frequently used for cyclopropanation, have been reviewed by Marchand and Brockway.In conjunction with a copper complex of an asymmetric ligand, ethyl diazoacetate will condense with 2,5-dimethyl-hexa-2,4-diene to give optically active chrysanthemic ester.With a cobalt complex of (+ )-camphorquinone dioxime, enantioselectivities as high as 70 % could be obtained in the addition of diazoacetate to 1,1-disubstituted olefins. As would be expected, choice of both metal and chelate is critical in such asymmetric syntheses. ...
