Synthesis of 2(1H)-Pyrazinone Phosphonates via an Arbuzov-type Reaction
摘要:
A simple and catalyst-free method for the synthesis of phosphonated 2(1H)-pyrazinones is described starting from 3,5-dichloropyrazinones. The method also works for 3-bromo- and 3-iodopyrazinones. Classical heating conditions as well as microwave-enhanced reaction conditions were tested.
