Synthesis of Selected 2-imidazolines (open access)

Synthesis of Selected 2-imidazolines

Since Djerassi and Scholz found that 2-(aryloxy-methyl)imidazolines and their hydrochloride salts exhibit vasoconstrictive properties, the 1,2-(I) 1,3-(II) and 1,4-bis-(2-imidazolinylmethoxy) benzene (III) analogs (Fig. 1, p.2) were chosen for synthesis in order to test them for their effective vasoconstrictive characteristics and for whatever other physiological properties they might exhibit.

Base Effects on the Thermal Decomposition of Sec-butyllithium Solutions (open access)

Base Effects on the Thermal Decomposition of Sec-butyllithium Solutions

The pyrolysis of sec-butyllithium in solution was studied in an attempt to understand the loss of stereo-specificity and the atypical kinetics that have been reported. Additionally, the effect of added lithium alkoxides was studied to determine their effects on the highly reactive sec-butyllithium substrate.

The Dropping Gallium Electrode in Fused Salts (open access)

The Dropping Gallium Electrode in Fused Salts

This paper is an attempt to appraise the usefulness of the dropping gallium electrode (DGE) in fused LiNO3-KNO3, to compare it with the dropping mercury electrode (DME), and to study the DGE in fused LiCl-KCl.

Naphth [2,3-d] Imidazoline-2,4,9-Triones (open access)

Naphth [2,3-d] Imidazoline-2,4,9-Triones

The study of some acylurea derivatives of 2-amino-3-alkylamino- and -3-arylamino-1,4-naphthoquinones was undertaken to determine the course of reaction under conditions similar to those used by J. R. Hoover and A. R. Day to prepare 2-alkyl-1H-naphth[2,3-d] imidazole-4.9-diones from 2-acylamino-3-amino-1,4-naphthoquinones.

Organomagnesium Compounds in Benzene Solvent and Their Application in Synthesis of Organoberyllium Compounds (open access)

Organomagnesium Compounds in Benzene Solvent and Their Application in Synthesis of Organoberyllium Compounds

The work reported by D. Bryce-Smith and G. F. Cox, along with several recent publications describing experimental results designed to elucidate the long disputed question of the structure of the Grignard reagent in ether stimulated the work reported here, in an effort to obtain additional evidence of the structure of the organomagnesium complex in benzene solvent. Since the primary objective of this work was to prepare organoberyllium compounds using the organomagnesium complexes in hydrocarbon solvents, it seemed an insight into the structure of these complexes would be beneficial in this work. The techniques used and experimental evidence obtained from the structure elucidation of the ethereal Grignard reagent have been most helpful in organization of the methods used to study the structure of organomagnesium halide complexes in benzene solvent. It seemed that an insight into the structure of these organomagnesium halide complexes in hydrocarbon solvents would be beneficial in accomplishing the second objective of this work. This objective was to prepare organoberyllium compounds using the organomagnesium halide complexes prepared in hydrocarbon solvents.
