ABSTRACT:
Novel N-alkoxycarbonyl- and N-alkoxythiocarbonyl-amidines and a process for the preparation of alkoxycarbonyl- and alkoxythiocarbonyl- amidines by reacting an amidine with an ester of chlorocarbonic acid or chlorothiocarbonic acid in the presence of an inorganic acid acceptor and a 2-phase aqueous/organic solvent mixture at from 0.degree. to 60.degree.0 C.
The novel end products which can be prepared by this process are useful starting materials for crop protection agents, and can be used in particular for the preparation of novel, selective herbicides.
