| titleOfInvention | New phenyl carbamates, process for preparing same and insecticidal compositions containing same |
| abstract | The invention comprises compounds of the general formula <FORM:0934282/IV(a)/1> in which R1 and R2 represent hydrogen atoms or methyl radicals and mixtures thereof with the corresponding o- and p-isomers and processes for their preparation by (a) reacting m-sec. butyl phenol or a mixture thereof with the o- and p-isomers with a carbamyl chloride or bromide R1R2NCOCl(Br), (b) reacting a chloroformate or carbonate ester of m-sec. butyl phenol or a mixture thereof with the o- and p-isomers with an amine R1R2NH, or (c) reacting m-sec. butyl phenol or a mixture thereof with the o- and p-isomers with methyl isocyanate to give the N-monoethyl compound. An isomeric mixture of sec. butyl phenols is prepared by alkylating phenol with n- or sec-butanol. Meta-sec. butyl phenol is prepared by a Grignard reaction between m-bromoanisole and methyl ethyl ketone followed by dehydration, hydrogenation and hydrolysis. Specification 852,920 is referred to.ALSO:A composition for combatting arthropods, particularly insects and ticks, comprises a phenyl carbamate of the general formula <FORM:0934282/VI/1> in which R1 and R2 represent hydrogen atoms or methyl groups, or a mixture thereof with the corresponding o- and p-isomers, together with a suitable carrier and/or distributing agent. The compounds may be formulated in any of the usual solid or liquid forms and the usual surfactants added. The compounds may be used in combination with other active ingredients such as insecticides, e.g. hexachlorocyclohexane, D.D.T., toxaphene, calcium arsenate or phosphoric acid esters, acricides or fungicides such as sulphur, phosphoric acid esters, N-trichloromethyl-sulphenyl tetrahydrophthalimide or methane sulphone - N - trichloromethylsulphenyl p-chloranilide. Examples describe the preparation of dusts, emulsifiable concentrates and sprays. The insecticidal activity is compared with that of known carbamate insecticides. Specification 852,920 is referred to. |
