Influence of Solvent from Which Crystals of 2-Amino-5-Aryl-1,3,4-Oxadiazoles Grow on Acetylation Reaction in Solid State
摘要:
The phenomenon of reaction anisotropy, i.e. forming of different products on different crystals' facets, is characteristic for 2-amino-5-aryl-1,3,4-oxadiazoles solid-state acetylation. In this case, the ratio of products in reaction yield depends on the form of substrate crystal, hence, on the solvent from which the crystal was grown. This hypothesis was confirmed by acetylation of different substituted 2-amino-5-aryl-1,3,4-oxadiazole crystals obtained from dimethylformamide, butyl alcohol and chloroform.
