The study of reactions of α-chlorocinnamonitriles with hydroxylamine
Autor: E. S. Balenkova, V. G. Nenajdenko, O. N. Lenkova, I. V. Golubinskii, Aleksey V. Shastin
Publikováno v: Russian Chemical Bulletin. 54:1728-1732
The E-isomers of α-chlorocinnamonitriles react with hydroxylamine to give a mixture of isomeric aminoisoxazoles, while the Z-isomers yield 3-aryl-2-chloroacrylamide oximes.
