A new method for the synthesis of 3-nitro-4H-pyran-4-ones is described involving nitration of acetylenic β-diketones.The 3-nitropyrones are converted into the corresponding 4-thiones which afford the respective 3-nitrooximes and N-methyl-4-thiopyridones o

3,5-Diphenyl-4-pyrone is nitrated in the phenyl groups under different conditions ortho and/or para to yield the 2,,2,,-di-, the 4,,4,,-di-, and the 2,,2,,,4,,4,,-tetranitro derivatives. 2,6-Diphenyl-4-pyrone undergoes meta nitration to give the 3,,3,,-dinitro derivative.
