Zur Kenntnis der Glucosonsäure (2‐Keto‐gluconsäure) (III. Mitteil.); mit einem Beitrag zur Konstitution der o ‐Phenylen‐diamin‐Verbindungen der Zucker)

2-Benzhydryl-7,7,8,8-tetracyanoquinodimethan

“…> TCNQ-1 TCNQ occur at +0.13 and -0.29 v. 3 The greater difficulty of reduction of 1 vs. TCNQ is evidence that the lack of planarity destabilizes the anion radical and dianion more than the parent quinodimethan, which is certainly in accord with expectation.…”

THE PREPARATION OF 2-(ALDO-POLYHYDROXYALKYL)-BENZIMIDAZOLES1

“…is indebted to the Wisconsin Alumni Research Foundation for a fellowship in 1935-36 and to the Graduate Research Fund for assistantships for 1936-39. We also wish to thank Dr. R. J. Dimler for the valuable assistance that he has given to this study 3. The imidazole structure was assigned by Hinsberg and Funcke (2) and confirmed by Ohle(3) in 1934.…”

The imidazole structure was assigned by Hinsberg and Funcke (2) and confirmed by Ohle(3) in 1934. In the same year Kuhn and Bar (5) prepared d-galacto-benzimidazole to test its reaction to sunlight irradiation as in the lumichrome and lumiflavin cleavages.…”

The Magnetic Study of the Equilibrium between Ferrohemoglobin, Cyanide Ion, and Cyanide Ferrohemoglobin

“…The preparation of benzimidazoles substituted in the [2] position by sugar residues was first reported by Griess and Harrow6 and was later studied by several other investigators. [6][7][8][9] Their method consisted in the evaporation of an aqueous solution of -phenylenediamine and an aldose, whereupon in most cases the desired product crystallized from the sirupy residue. The yields were very poor and in many cases involved by-products of the quinoxaline type.…”
