Abstract:
The present invention relates the use of 2,3-dihalonaphthoquinone compounds of Formula I wherein R1 and R2 are leaving groups like halogens selected from the group comprising Cl, Br, I and F and the R1 and R2 may be the same halogen or may contain different halogen groups, or sulphonyl groups, for making napthoquinone compounds of Formula IA wherein X is any aryl, heteroaryl, alkyl, cyclohexyl, substituted cylohexyl groups and the like.
