Abstract
Abstract N-carboxylated N-methylcarbamic acid aryl esters of the general formula ##EQU1## in which Ar is phenyl, naphthyl, dihydrobenzofuranyl or indanyl optionally substituted by alkyl, alkenyl, alkynyl, alkoxy, alkenoxy, alkynoxy, alkylmercapto, alkenylmercapto, alkynylmercapto, dialkylamino, trihalomethyl, halogen, nitro, cyano, cycloalkyl, formamidino, dioxolanyl, dioxanyl or dialkoxymethyl, and R is OAr or optionally substituted alkoxy, alkenoxy, alkynoxy, cycloalkyloxy, amino, alkylmercapto or arylmercapto, Which possess insecticidal and acaricidal properties.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
An N-carboxylated N-methylcarbamic acid aryl ester of the formula ##EQU6## in which Ar is phenyl, naphthyl, or phenyl or naphthyl substituted one or more times by a lower alkyl, alkenyl, alkynyl, alkoxy, alkenoxy, alkynoxy, alkylmercapto, alkenylmercapto or alkynylmercapto each of up to 4 carbon atoms, or by dimethylamino, trifluoromethyl, chlorine, bromine, fluorine nitro, cyano, cycloalkyl of 5 or 6 ring carbon atoms substituted with lower alkyl of 1 to 4 carbon atoms, or by N,N-dimethyl- or N,N-diethylformamidino, or by a lower dialkoxymethyl radical; and R is optionally substituted lower alkoxy, alkenoxy, alkynoxy or alkylmercapto each with 1 to 4 carbon atoms, or anilino, chloranilino, nitroanilino, methoxy anilino, or --NR' 2 wherein R' is individually selected from the group consisting of hydrogen and alkyl, alkenyl, cycloalkyl or cycloalkenyl each of up to 12 carbon atoms, phenylmercapto or phenylmercapto substituted by lower alkyl of 1 to 4 carbon atoms or chlorine, or OAr.
Claim 2
Dependent Claim
151 words
An N-carboxylated N-methylcarbamic acid aryl ester of the formula ##EQU6## in which Ar is phenyl, naphthyl, or phenyl or naphthyl substituted one or more times by a lower alkyl, alkenyl, alkynyl, alkoxy, alkenoxy, alkynoxy, alkylmercapto, alkenylmercapto or alkynylmercapto each of up to 4 carbon atoms, or by dimethylamino, trifluoromethyl, chlorine, bromine, fluorine nitro, cyano, cycloalkyl of 5 or 6 ring carbon atoms substituted with lower alkyl of 1 to 4 carbon atoms, or by N,N-dimethyl- or N,N-diethylformamidino, or by a lower dialkoxymethyl radical; and R is optionally substituted lower alkoxy, alkenoxy, alkynoxy or alkylmercapto each with 1 to 4 carbon atoms, or anilino, chloranilino, nitroanilino, methoxy anilino, or --NR' 2 wherein R' is individually selected from the group consisting of hydrogen and alkyl, alkenyl, cycloalkyl or cycloalkenyl each of up to 12 carbon atoms, phenylmercapto or phenylmercapto substituted by lower alkyl of 1 to 4 carbon atoms or chlorine, or OAr.
