Description
Summary:A procedure on palladium‐catalyzed carbonylative reaction of trifluoroacetimidoyl chlorides and nitro compounds for the construction of pharmaceutically valuable 2‐(trifluoromethyl)quinazolin‐4(3H)‐ones has been achieved. In this transformation, Mo(CO)6 has been used both as a convenient CO source and a reducing reagent. This newly developed protocol is compatible with various nitro compounds and can be readily scaled up to 1 mmol scale.
