Preparation of Heteroarenecarbonitriles by Reaction of Heteroarene N-Oxides with Trimethylsilyl Cyanide in the Presence of DBU
摘要:
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.
