Недостатком известного способа вл етс низкий выход целевого продукта , использование в качестве од ,ного из реагентов взрыво-и пожароопасного металлического натри .The disadvantage of this method is the low yield of the target product, the use of explosive and flammable metallic sodium as one of the reactants.
Цель изобретени - повьииение выхода , упрощение процесса и расширение ассортимента целевых продуктов.The purpose of the invention is to increase the yield, simplify the process and expand the range of target products.
Указанна цель достигаетс пред% Слагаемым способом получени соединений формулы I, заключающимс в г том, что на 4-замещенные 1,2,3-селенодиазолы действуют сильным основанием , например едким кгши, с последующей обработкой полученных при этом соединений фенилизотиоцианатом и ,в среде растворител такого, как диметилформамид (ДМФА). Выход 40,5157 ,7%.This goal is achieved by the% Compound method for preparing compounds of the formula I, consisting in the fact that 4-substituted 1,2,3-selenodiazoles act with a strong base, such as caustic mixture, followed by treatment of the compounds obtained with phenyl isothiocyanate such as dimethylformamide (DMF). Yield 40.5157, 7%.
Указанные услови проведени процесса позвол ют повысить выход целевых продуктов, исключить необходимость использовани металлического натри . Кроме того, предлагаемым способом можно получить новые соединени .The specified process conditions allow increasing the yield of the target products, eliminating the need to use metallic sodium. In addition, the proposed method can produce new compounds.
