In contrast with the Schiff base salen, salicylaldehyde oxime (79) (salox) complexes of Co have received comparatively little attention, but a series of bis-bidentate divalent complexes of the form iraiis-Co(sa 1 ox)2( D M SO)2 have been reported.343 The heterocyclic bidentate oxime violurate (lH,3H-pyrimidine-2,4,5,6-tetrone 5-oximate, Hvi) (80) and its /V-methyl (mvi) and /V,/V -dimethyl (dmvi) derivatives form high-spin divalent [Co(vi)]+ and Co(vi)2 complexes, whereas [Co(vi)3] is low spin.344 The mixed-ligand Co(dmvi)2(phen) complex is also low spin. The crystal structure of m-Co(pxo)2Br2 (pxo = 2-acetylpyridine-l-oxide oxime) is isostructural with the Ni11 relative.345 The dichloro complex also adopts a cis configuration. The tridentate dioximes 2,6-diformyl-4-methylphenol dioxime and 2,6-diacetyl-4-methylphenol dioxime (Hdampo) form binuclear complexes of the type (81a) and (81b) respectively.346 Cobalt oxide nanoparticles were prepared by... 

Amperometric method for the study of precipitation reactions, e.g., salicylaldoxime (or salicylaldehyde oxime), dimethylglyoxime, have been used for such type of studies. 

An excellent protocol for the cycUsation of salicylaldehyde oximes (or ort/to-hydroxyaryl-ketoximes) is the apphcation of Mitsnnobn-type conditions the combination triphenylphosphine/DDQ is also very efficient. Phenyliodine(lll) bis(triflnoroacetate) (PIFA) can be used to effect ring closnre of ort/to-amino-arylcarboxamides giving indazohn-3-ones or of ort/to-thiol-arylcarboxamides, to give benzisothiazol-3-ones. ... 

The generation of a chlorosulfide serves the purpose in the opposite sense. Probably the best method for the cyclisation of salicylaldehyde oximes (or orr/zo-hydroxyar-ylketoximes) is the application of Mitsunobu-type conditions, ... 

Vanderwal and Jacobsen have used an aluminium complex of the Jacobsen salene to catalyze asymmetric additions of salicylaldehyde-oxime to alkenoylamides (Scheme 17a) [96]. The peculiar oxime nucleophile was needed as ordinary alcohols... 

The spin-lattice relaxation was studied in more detail in a ferric triangle, [Fe3(p3-0)(02CPh)s(salox)(EtOH)(H20)] (Fessalox, H2salox = salicylaldehyde oxime) [150]. Inversion recovery measurements at X-band frequencies yielded... 

Salicylaldehyde oxime (salicylaldoxime) (1%). Dissolve Ig salicylaldoxime, CsH4 CH(NOH) - OH, in 5 ml cold 96% ethanol and pour the solution dropwise into 95 ml water at a temperature not exceeding 80°C. Shake the mixture until clear, and filter if necessary.

Salicylaldehyde oxime allowed to react with acetic anhydride in the presence of 70%-HC104 2-methyl-4H-l,3-benzoxazin-4-onium perchlorate. Y 95%. F. e., also from salicylonitrile, s. G. N. Dorofeenko, Y. I. Ryabukhin, and V. V. Mezhe-ritskii, Zh. Org. Khim. 10, 2233 (1974) C. A. 82, 43292. 

The synthesis of many metal derivatives of complexing agents such as 8-hydroxyquinoline and salicylaldehyde oxime begins with aqueous solutions of metal ions e.g. sulfates, nitrates, etc.). Addition of the ligand and suitable control of pH allows either precipitation of the coordination compound or its extraction into nonprotic media for either qualitative determination or work up (Eqs 6.14 and 6.15 ). 

Benzisoxazoles.—The reaction of salicylaldehyde oxime with thionyl chloride in pyridine to yield 1,2-benzisoxazole (539 R = H) constitutes a new synthesis of this ring system.Thermolysis of the azido-ketone (540) affords the linearly annelated anthranil (541). ° The benzisoxazoles (539 R = H, Me, or Ph) rearrange photochemically to the benzoxazoles (543) via intermediate azirines (542). ° Irradiation of an aqueous solution of the benzisoxazolium salt (544) gives the phenolic ketone (545). ° ... 

A wide variety of nickel chelates, e.g, Ni complexes of dithioic acids (NiDRC and NiDRP), salicylaldehyde oximes (33), thiobisphenolates (cyasorb UV 1084, 31) and hydroxybenzyl phos-phonates (Irgastab 2001 30), all of which are good UV stabilizers, " are substantially lost during the photooxidative induction period (Figure 5, where R = butyl).
