A compound having the structural formula <IMAGE> where R is C1-C6 alkyl or C5-C6 cycloalkyl; X is hydrogen or methyl; R1, R2, R3 and R4 are the same or different and are hydrogen, halogen, C1-C8 alkyl, C1-C2 haloalkyl, C3-C6 cycloalkyl, C7-C9 aralkyl, phenyl, nitro, C1-C6 alkoxy, C1-C6 alkylthio, C1-C6 alkylsulfinyl, C1-C6 alkylsulfonyl, C7-C9 aralkoxy, phenoxy, phenylthio, phenylsulfinyl, phenylsulfonyl, tetrahydro-2-thienyl, dioxytetrahydro-2-thienyl, alkali metal carboxylate, C2-C5 alkoxycarbonyl, phenoxycarbonyl or N(R5)R6; R5 and R6 are the same or different and are hydrogen or C1-C2 alkyl; and n is 0, 1 or 2 is disclosed. A method for controlling insects using an insectidically effective amount of this compound is also taught. In addition, an insecticidal composition comprising an insecticidally effective amount of the compound and a carrier therefor is provided. The disclosure further sets forth a compound having the structural formula <IMAGE> where R1, R2, R3 and R4 are the same or different and are hydrogen, halogen, C1-C8 alkyl, C1-C2 haloalkyl, C3-C6 cycloalkyl, C7-C9 aralkyl, phenyl, nitro, C1-C6 alkoxy, C1-C6 alkylthio, C1-C6 alkylsulfinyl, C1-C6 alkylsulfonyl, C7-C9 aralkoxy, phenoxy, phenylthio, phenylsulfinyl, phenylsulfonyl, tetrahydro-2-thienyl, dioxytetrahydro-2-thienyl, alkali metal carboxylate, C2-C5 alkoxycarbonyl, phenoxycarbonyl or N(R5)R6; R5 and R6 are the same or different and are hydrogen or C1-C2 alkyl; and n is 0, 1 or 2 with the proviso that when R2, R3 and R4 are all hydrogen and n is 0, R1 cannot be methyl, This class of compounds is used in the process, disclosed herein, for making the carbamate compounds of the present invention.
