The present invention relates to herbicidally active cinnolinium derivatives of formula (I), as well as to processes and intermediates used for the preparation of such derivatives. The invention further extends to herbicidal compositions comprising such derivatives, as well as to the use of such compounds and compositions in controlling undesirable plant growth: in particular the use in controlling weeds, in crops of useful plants.
The present invention relates to herbicidally active cinnolinium derivatives and formulations comprising such derivatives. The invention further extends to herbicidal mixtures comprising a cinnolinium derivative as described herein and at least one additional herbicidal active ingredient. The use of the afore-mentioned cinnolinium derivatives, formulations and/or herbicidal mixtures in controlling undesirable plant growth: in particular the use for the post-emergence control of weeds, also falls within the scope of the present invention.

The lithiation of 3-, 4-chloro and 3-, 4-methoxycinnolines was studied and good yields were obtained. When iodine was used as electrophile, 4,8-diiodo or 4,8-iodochloro compounds were prepared. A xanthone and diazepines were synthetized.
