    Abstract: Sterically hindered phosphoramidates such as N, N'-bis[di-(2,6-xylenoxy)phosphinyl]piperazine are prepared by the reaction of a sterically hindered diaryl chlorophosphate, such as di-(2,6-xylyl) chlorophosphate, with a basic nitrogen compound containing at least two basic N-H groups, preferably a heterocyclic compound such as piperazine, in a predominantly liquid, solvent-free reaction mixture. The reaction my be conducted in the melt or in the presence of a non-solvent carrier, typically an aliphatic hydrocarbon. An excess of the basic nitrogen compound is employed as an acid acceptor.

    Abstract: 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.
