Isomerization of N,N,N′-trifluoroalkylamidines

Conclusions The syn-isomers of N,N,N-trifluorobutyramidine and N,N,N-trifluoromonochloroacetamidine are isomerized in the presence of HCl to the anti-form. The isomerization of the syn-isomer of N,N,N-trifluoromonochloroacetamidine also proceeds in the presence of ethanol.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2159–2160, September, 1973.
