COBALT(II) NITRATE HEXAHYDRATE 98+% A.C.S. REAGENT (C005B-002942)

Application

Cobalt(II)nitrate hexahydrate can be used as a catalyst to synthesize:

• 5-Carboxanilide-dihydropyrimidinone derivatives by the condensation of acetoacetanilides, aldehydes, and urea/thiourea.
• Nitro indoles by the nitration of indoles using tert-butyl nitrite as the nitro source.
• Quinazolinones from 2-aminobenzonitriles using alcohols in the presence of phosphine ligand.
