Schroer, Hans P. published the artcileBehavior of some metal halides toward dimethyl glycol ether, Name: Cobalt(II) dibromo(1,2-dimethoxyethane), the publication is Zeitschrift fuer Chemie (1967), 7(6), 238, database is CAplus.
Some metal halides (I), gave adducts with dimethyl glycol ether (II) in the absence of moisture and of air. The adducts prepared were (I, I:II molar ratio in the adduct, and color given): CoBr2, 1:1, blue; CoCl2, 1:1, blue; FeCl3, 1:1, yellow brown; FeCl2, 1:1, white; CdI2, 1:1, colorless; NiBr2, 1:2, orange; CuCl2, 1:0.5, brown; MoCl3, 1:1, red.
Zeitschrift fuer Chemie published new progress about 18346-57-1. 18346-57-1 belongs to bromides-buliding-blocks, auxiliary class Cobalt, name is Cobalt(II) dibromo(1,2-dimethoxyethane), and the molecular formula is C4H10Br2CoO2, Name: Cobalt(II) dibromo(1,2-dimethoxyethane).
