Synthesis of 1-benzyloxy-2(1H)-pyrazinones having substituents at C-5 and C-6 positions and their photochemical behavior have been studied. Upon irradiation 1-benzyloxy-2(1H)-pyrazmones underwent N-O bond cleavage in high quantum yields. The rearrangement of the benzyioxy group to C-3 position of the ring and [2+2] cycloaddition were also observed.

A series of 2-hydroxypyrazine 1-oxides were prepared from the corresponding chloropyrazines by two methods, including oxidation processes in satisfactory yields.The treatment of 2,3-diphenylpyrazine 1,4-dioxide (6) led to 2,3-dichloro-5,6-diphenylpyrazine
