4-ethyl-3-(substituted phenyl)-1-(3-trifluoromethylphenyl)-2-pyrrolidinone derivatives |
摘要 |
4-Ethyl-3-(phenyl)-1-(3-trifluoromethylphenyl)-2-pyrrolidinones (I) and corresponding compounds bearing a p-substituent on the 1-position phenyl group and/or a substituent on the 3-position phenyl group exhibit selective herbicidal activities against various weeds which cause problems in rice or upland fields, even at extremely low application rates. They can be prepared by reductive dehalogenation of a corresponding alpha -haloethyl substituted pyrrolidinone or reductive cyclization of a corresponding N-2-butenyl-N-(substituted phenyl)-haloacetyl-3-trifluoromethylaniline. <CHEM> y |
