Approximately 20 N-methylcarbamates and the corresponding monothiophosphates of substituted 2,2,2-trifluoroacetophenone oximes have been synthesized and their insecticidal activity examined. This activity has been compared to their corresponding anticholinesterase values. The carbamate exhibiting the highest anticholinesterase activity contained an ortho methoxy substituent.The toxicity to house flies by topical application was less than expected, but the activity was raised to the expected level by synergism with pi-
Catalytic liquid and vapor phase proceesea for the preparation of %butenenitrile from allyl chloride and hydrogen cyanide are described. Various sulfides were prepared by the free radical-catalyzed addition of thiols to 3-butenenitrile1 bbutenoic acid and esters, and were oxidized to the respective sulfones. Relative rates of isomerization of 3-butenenitrile to 2-butenenitrile using various amine catalysts were determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
