The above results furnish conclusive proof that the two diazo compounds have an asymmetric structure, in part. This is most simply explained by the electronic formulas
The inner ammonium salt of 2-amino-4-glyoxalinesulfonic acid has been prepared. On boiling with sodium hydroxide, the sodium salt of the acid is obtained.2. 2-Hydroxy-4-glyoxalinesulfonic acid has been prepared.3. 2-Phenyl-4-glyoxalinesulfonic acid has been prepared. Boulder, Colorado
of the decomposition being the yellow, crystalline compounds dehydrorotenone and rotenonone.3. Similar changes are undergone by dihydrorotenone and isorotenone in pyridine solution, analogous compounds no doubt being formed.4. Dry, crystalline rotenone undergoes no change on long standing.
Oxygen consumption studies on the formation of the oxidized complexes similar to those described in the study of the thioglycolic acid complexes show that one equivalent of oxygen is taken up for each mole of cobalt.
SummaryA number of cobalt complexes of cysteine in both reduced and oxidized states have been crystallized and their chemical constitutions, properties and interrelationships discussed.New York, N. Y.
Reaction of Monomeric Adipic Anhydride with Anihe.-One cubic centimeter of anhydride was added to about eight cubic centimeters of aniline with stirring. Reaction was immediate and much heat was evolved. The excess aniline was dissolved in dilute hydrochloric acid. The solution was diluted to 200 cc. and filtered. The crude product was dried and weighed; m. p. 152-153'; yield 80%. The monoanilide of adipic acid has previously been prepared by heating CsHsNHCOCH(C0OH) (CH2)&OOH.E Recrystallization from water did not raise the melting point. The crude compound was completely soluble in hot water (absence of dianilide). A similar experiment was carried out and worked up in smaller volume; m. p.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
