| titleOfInvention | 3-benzyl hydantoins |
| abstract | The invention comprises 3-benzyl hydantoins of formula <FORM:1074999/C2/1> wherein R1 is a C1-C3 alkyl group and R2 is a benzyl radical which may be substituted by 1 or 2 chlorine atoms or an a -methyl group. They may be prepared by cyclization with dilute mineral acid of the corresponding hydantoate compound which is prepared by converting the appropriate amine acid ester to the corresponding isocyanato compound by reaction with phosgene which is then reacted with a suitably substituted benzylamine. The compounds are herbicides (see Division A5). The examples describe the preparation of 3-benzyl-5-methyl-, 3 - (2 - chlorobenzyl) - 5 - methyl -, 3 - (4 - chlorobenzyl) - 5 - methyl -, 3 - (a - methylbenzyl) - 5 - methyl -, 3 - benzyl - 5 - ethyl -, 3 - benzyl - 5 - isopropyl -, 3 - (2 - chlorobenzyl) - 5 - isopropyl - and 3 - (2,4 - dichlorobenzyl) - 5 - isopropyl-hydantoins. Also described is the preparation of ethyl-2-isocyanatopropionate, ethyl 2-isocyanatobutanoate, and ethyl 2-isocyanato-3-methyl butanoate.ALSO:Herbicidal compositions comprise 3-benzyl hydantoins of formula <FORM:1074999/A5-A6/1> wherein R1 is a C1-C3 alkyl group and R2 is a benzyl group which may be substituted by 1-2 chlorine atoms or an a -methyl group, in conjunction with an inert carrier which may be solid or liquid. The compositions can also include surfactants, humectants, oils, contact agents or other herbicides such as sodium chlorate, borax and sodium metaborate, 2, 3,6-trichloro - benzyloxypropanol, the chloro - phenoxy acetic acids, trichlorobenzoic acids, substituted ureas, triazines uracils and carbomates. The compositions are useful for pre-or post-emergence treatment. |
