Certain fluoroalkanoic acids and derivatives, including 2-fluoroisobutyric acid and 2-fluoroisobutyryl chloride, useful as intermediates for fungicides, and methods of preparing them.

Fungicide intermediates

Fungicidal compounds of formula (I): ##STR1## in which X and Y are independently O or S, and A and R.sup.1 to R.sup.4 have various specified values.

Fungicides

Pyrimidine compounds useful as plant growth regulators have the formula (I): ##STR1## wherein Y is an optionally substituted secondary or tertiary alkyl group containing from 3 to 7 carbon atoms or an optionally substituted cycloalkyl or alkylcycloalkyl group containing from 3 to 7 carbon atoms; R.sup.1 and R.sup.2, are hydrogen or a lower alkyl group; A is an optionally substituted phenyl group; n is an integer which may be 1 or 2; and R.sup.3 is hydrogen, an alkyl group containing from 1 to 4 carbon atoms, or an alkenyl or alkynyl group containing from 2 to 4 carbon atoms.

Pyrimidine compounds

Pyrimidine compounds useful as plant growth regulators have the formula (I): ##STR1## wherein Y is an optionally substituted secondary or tertiary alkyl group containing from 3 to 7 carbon atoms or an optionally substituted cycloalkyl or alkylcycloalkyl group containing from 3 to 7 carbon atoms; R.sup.1 and R.sup.2, which may be the same or different, are hydrogen or a lower alkyl group; A is an optionally substituted heterocyclic group, for example thienyl or pyridyl; n is an integer which may be from 0 to 2 and is preferably 0; and R.sup.3 is hydrogen, an alkyl group containing from 1 to 4 carbon atoms, or an alkenyl or alkynyl group containing from 2 to 4 carbon atoms.

Pyrimidine derivatives

The present invention relates to a class of novel chloro-substituted ketone imidazole derivatives. The invention further relates to pharmaceutical compositions containing such compounds and to the use of such compounds and compositions as anti-anaerobic agents.
