Abstract

NEW MATERIAL:A urea derivative expressed by formula I (X is halogen, alkyl or trifluoromethyl; n is an integer 0W3; R is methyl or methoxy).
EXAMPLE: N'-4-[ 4-( 3-Methyl-4-chlorophenoxy )2-butynyloxy ]phenyl-N-methyl-N- methoxyurea.
USE: A selective herbicide having a high safety for crops and high harbicidal activity against weeds.
PROCESS: A butynyl halide derivative expressed by formula II (Y is halogen) is reacted with a urea derivative expressed by formula III in a solvent, e.g. benzene or methanol, in the presence of an acid acceptor, e.g. pyridine or caustic soda, under cooling or heating for 1W8hr to give the compound expressed by formula I.
