Abstract
Title cpds are of formula: (I) where R and R1 are different and are selected from H, halogen, alkyl trihalomethyl, OH, alkoxy, formyl, NO2, sulphamoyl, SH or alkylthio. They are prepd. by the condensn. of two o-nitrotoluenes at -5 degrees to +10 degrees C in an inert solv. in the presence of a base and an oxidising agent. In an example 58 parts o-nitrotoluene and 73 pts. 2-NO2-4-Cl toluene were reacted in ether in the presence of 143 parts K. tert butoxide and 206 parts benzoyl peroxide at 0 degree C, and the product chromatographed to give (I), R = H, R1 = 4-Cl.
