Synthèse des 1,2,4-triazoles et des 1,2,4-triazin-6-ones à partir des N1-tosylamidrazones
Written by sctunisie no commentsThe condensation of tétraéthyl orthocarbonate with N1-tosylamidrazones in the presence of acetic acid gives 1,2,4-triazoles with good yields. In basic medium, the reaction of a variety of N1-tosylamidrazones with α-bromoesters gives 1,2,4-triazin-6-ones.
