摘要:
This invention pertains to processes for the preparation of nuclear substituted benzylic halides such as ortho-amino benzyl chlorides by reaction of substituted benzyl sulfoxides with nonoxidizing acid halides.
摘要:
The disclosure herein relates to tertiary 2-haloacetamides substituted on the amide nitrogen atom with certain 1-cycloalken-1-yl, alkoxymethyl, alkylthiomethyl or acetamidomethyl radicals. These acetamides are useful as herbicides.
摘要:
The disclosure herein relates to a new process for the preparation of N-(halomethyl) acylamides by reacting the corresponding N-(alkoxymethyl) acetamide with a hydrogen halide.
摘要:
The disclosure herein pertains to the preparation of N-(alkoxymethyl)- and other N-methylene ether-substituted 2-haloacetamides from other N-methylene ether-substituted 2-haloacetamides and the appropriate alcohol by a transetherification process.
摘要:
The disclosure herein relates to a new class of herbicidal compounds comprising 2'-alkyl-6'-(2,2-dialkoxyethyl)-N-(alkoxymethyl)-2-haloacetanilides, herbicidal compositions containing same, their method of preparation and use to selectively control undesired vegetation in agricultural crops, e.g., monocotyledons such as wheat, sorghum and rice and dicotyledons such as sugarbeets and soybeans.
摘要:
Disclosed herein are dihydropyridine dicarboxylic acid amide derivatives which are useful as herbicides, and herbicidal compositions and methods using same.
摘要:
The disclosure herein relates to a group of N-hydrocarbyloxymethyl-2-haloacetanilide compounds, herbicidal compositions containing said compounds as the active ingredient and herbicidal method of use in various crops, particularly, corn and soybeans and other crops including cotton, peanuts, rape and bush beans. The herbicides herein are particularly effective against hard-to-kill perennial weeds such as quackgrass and nutsedges and are also effective against annual weeds.
摘要:
This invention relates to a process for preparing 2'-methyl-2-haloacetanilides by selective catalytic hydrogenation of 2'-(halomethyl)-2-haloacetanilides. The 2'-(halomethyl)-2-haloacetanilides are initially prepared by reacting an ortho-(halomethyl) aniline or its anilinium salt with a haloacetyl halide.
摘要:
This invention pertains to a process for preparing substituted and unsubstituted benzotrichlorides. The process generally involves reacting the starting compound with a perchloroalkane with presence of base and a phase transfer catalyst.
摘要:
The disclosure herein relates to substituted 2-alkylsulfonylalkyl nitrobenzenes and a process for the preparation thereof. The compounds herein are useful as intermediates in the preparation of certain substituted anilines used as reactants in the preparation of 2-haloacetanilide herbicides.
