AbstractA simple and efficient one-potsynthesis was developed for the preparation of S-alkyl thiolcarbamates from xanthogenate without catalyst using water as a solvent. The water can be recycled after removal of the product. The significant features of this protocol are: operational simplicity, mild reaction conditions, recycling of solvent and high product yields. Starting basic alkyl xanthogenate
N-(haloacyl)-5-(substituted phenyl)-oxazolidines as new compounds having the formula
wherein R is C1-C10 haloalkyl, C1-C20 alkyl, C1-C6 cycloalkyl, C1-C6 haloalkenyl or C1-C6 alkylthio; X is C1-C4 alkyl, C1-C4 alkoxy, C1-C4 haloalkyl or halogen; and n is the integer 1 to 5, inclusive, with the proviso that where X is trifluoromethyl, R is other than 3-chloropropyl; useful as antidotes to protect against thiocarbamate or acetanilide herbicides when applied by various methods and improved herbicidal composition comprising an herbicidally effective amount of a thiocarbamate or acetanilide herbicide and an antidotally effective amount of said antidote compounds.
