This invention relates to pyrimidine derivatives, to compositions comprising the pyrimidine derivatives, to methods of making and using these compositions, and to the use of the pyrimidine derivatives as adjuvants, particularly for agrochemical use. In particular, the present invention relates to compositions comprising the pyrimidine derivatives selected from emulsifiable concentrates (EC), emulsions in water (EW), suspensions of particles in water (SC), soluble liquids (SL), capsule suspensions (CS), suspensions of particles with an emulsion (SE), dispersion concentrates (DC), suspensions of particles in oil (OD), water dispersible granules (WG), soluble granules (SG) and wettable powders (WP).

Pyrimidine derivatives

Pyrandione, thiopyrandione and cyclohexanetrione compounds of formula (I), which are suitable for use as herbicides. 

Herbicides

A microencapsulated catalyst is prepared by dissolving or dispersing a catalyst in a first phase (for example an organic phase), dispersing the first phase in a second, continuous phase (for example an aqueous phase) to form an emulsion, reacting one or more microcapsule wall-forming materials at the interface between the dispersed first phase and the continuous second phase to form a microcapsule polymer shell encapsulating the dispersed first phase core and optionally recovering the microcapsules from the continuous phase. The catalyst is preferably a transition metal catalyst and the encapsulated catalyst may be used for conventional catalysed reactions. The encapsulated catalyst may recovered from the reaction medium and re-cycled.
