A Facile Synthesis of N-Arylcyanoformamidoximes, 4-Aryl-3-cyano-1,2,4-oxadiazin-5(6H)-ones, 2-Cyanoquinazoline-3-oxides, and 2-Cyanoquinazolines via 5-Arylimino-4-chloro-5H-1,2,3-dithiazoles
Several heteroarenecarbonitriles were prepared from the corresponding heteroarene N-oxides by treatment with trimethylsilyl cyanide (TMSCN) in the presence of a base in tetrahydrofuran (THF). 1,8-Diazabicyclo[5.4.0]-7-undecene (DBU) was found to be an effective base for the cyanation.
