摘要

According to literature, phosphorus pentoxide, 1 titanium tetrachloride, 2 thionyl chloride, 3 and trifluoroacetic anhydride 4 are some reagents used to prepare nitriles through primary amide dehydration. In addition, more recently, methods using other reagents to perform the dehydration under milder conditions, such as PyBOP, 5 EDCI, 6 and cyanuric chloride, 7 have been reported. All of these methods are characterized by a common requirement, that is, the ...
