Chlorination of Platinum-Bound Salicylaldoxime. The First Example of a Structurally Characterized Monodentate Salicylaldoxime-Type Ligand

“…This purely organic material was formed by the chlorination of a mixture of salicylaldoxime complexes, prepared in agreement with Cox et al, [19] and was separated mechanically upon fractional crystallization of the products of the reaction from an acetone/toluene [21] ). …”

“…The oxime 3,5,2-Cl,Cl,HOC 6 H 2 CHϭNOH was prepared earlier by the chlorination of salicylaldehyde to give 3,5,2-Cl,Cl,HOC 6 H 3 CHϭO and its subsequent condensation with hydroxylamine. [21] We have also observed that when nitrosyl chloride is used instead of molecular chlorine, only oxidation of the central ion is observed, to give [PtCl 2 (o-OC 6 H 4 CHϭNOH) 2 ] (4), and the benzene rings remain intact.…”

The Action of Amylases in Relation to the Structure of Starch and Its Metabolism in the Plant. Parts I‐iii

“…The fact must now be considered that determinations of particle size by a variety of physical methods indicate much higher values. Molecular weight values ranging from 20,000 to 200,000 have been reported, based on observations of viscosity (Staudinger & Eilers, 1936), sedimentation rate (Lamm, 1934), osmotic pressure (Samec, 1927;Carter & Record, 1936) and dialysis coefficient (Brinzinger & Brinzinger, 1931).…”

“…In a few other cases, an iodine coloration is given by substances (other than starch products) in which the property appears clearly related to their colloidal or semi-colloidal state (e.g. lathanium subacetate (Biltz, 1904), saponarin and cholalic acid (Barger & Field, 1912).…”

The meta Cleavage of Catechol by Azotobacter Species

“…3-Chlorocatechol was prepared by the methods of Willstatter and Muller [17], and Willstatter and Pfannenstiel [18]. 4-Chlorocatechol was synthesized by the method of Dakin [19], and 3,5-dichlorocatechol was obtained by a Dakin oxidation [19] of 4,6-dichlorosalicylaldehyde, prepared according to the procedure of Biltz and Stepf [20].…”
