| Abstract: | 2-Aryl(heteryl, dimethylamino)-6-bromomethylidene-4,4-dimethyl-5H-1,3,4-oxadiazinium bromides were prepared in good yields by the reactions of 1-aroyl(heteroyl)-2,2-dimethylhydrazines and 1,1,4,4-tetramethylsemicarbazide with 1,3-dibromopropyne in MeOH or MeCN at 20–50°C.__________Translated from Zhurnal Obshchei Khimii, Vol. 75, No. 3, 2005, pp. 473–475.Original Russian Text Copyright © 2005 by Nakhmanovich, Elokhina, Larina, Abramova, Lopyrev. |
