Abstract
A process for preparing 2-pyrimidinecarboxylates of the general formula: ##STR1## wherein R is C.sub.1-6 -alkyl, C.sub.3-6 -cycloalkyl, aryl or arylalkyl, and R.sup.1 to R.sup.3 are, independently of one another, hydrogen, C.sub.1-6 -alkyl, fluorinated C.sub.1-6 -alkyl, C.sub.1-6 -alkoxy, (C.sub.1-6 -alkoxy)-C.sub.1-6 -alkyl or (C.sub.1-6 -alkoxy)carbonyl. These are obtained from the corresponding 2-halopyrimidine, the corresponding alcohol ROH and carbon monoxide in the presence of a palladium/phosphine complex and a base. 2-pyrimidinecarboxylates are intermediates for preparing herbicides.
