Abstract

Описывается способ получения диазоалканов, при котором диазоалкан-прекурсор растворяется в первом растворителе, основание растворяется во втором растворителе, вещества в реакционном сосуде вступают в реакцию с образованием диазоалкана, и полученный диазоалкан отводится при пониженном давлении. Способ особенно пригоден для получения диазометана.
