Gf. Lai et al., A one-pot method for the efficient preparation of aromatic nitriles from aldehydes using ammonia, magnesium sulfate, and manganese dioxide, SYNLETT, (2), 2001, pp. 230-231
A one-pot and efficient preparation of aromatic nitriles from the correspon
ding aldehydes was accomplished by treatment with 2 M ammonia solution in 2
-propanol, magnesium sulfate, and manganese dioxide in THF at room temperat
ure. This method was found to be compatible with a variety of functionaliti
es such as hydroxyl, ester, and amide.
