The synthesis of some novel 3, 3, 5, 7-tetranitrooxindoles and 4, 4-dinitropyrazol-5-ones and their behaviour towards various nucleophiles and electrophiles are reported. Reactions with hydroxide ions or secondary amines produced salts of eg 2-amino-3, 5- dinitrophenyldinitromethane, which subsequently could be further transformed into indazoles, indoles or benzoxazinones depending upon substrate and conditions used. ...
