REACTION OF AMIDOXIMES WITH α-CHLOROACID CHLORIDES: NOVEL SYNTHESIS OF 1,2,4-OXADIAZIN-5-ONES
Hussein, Ahmad Q.
, p. 163 - 173 (2007/10/02)
The reaction of amidoximes with α-chloroacid chlorides gives under thermal reaction conditions 5-(1-chloroalkyl)-1,2,4-oxadiazoles.In presence of a strong base, the reaction follows a different path leading to the formation of 4H-1,2,4-oxadiazin-5(6H)-one
