Claim 1
Independent Claim
87 words
An insecticidal compound of the formula: ##STR3## in which R is an alcohol residue selected from the group consisting of: (a) a benzyl- or phenoxy-substituted benzyl group of the formula: ##STR4## wherein Z is hydrogen, methyl, cyano, ethynyl, or phenyl, and Z is --O-- or --CH 2 --; (b) a benzyl- or phenoxy-substituted furylmethyl group; (c) an imidomethyl group selected from the group consisting of maleimidomethyl, phthalimidomethyl, and tetrahydrophthalimidomethyl; and (d) a benzyl group substituted in at least two ring positions with chloro, methyl, or methylenedioxy group.
Claim 2
Dependent Claim
87 words
An insecticidal compound of the formula: ##STR3## in which R is an alcohol residue selected from the group consisting of: (a) a benzyl- or phenoxy-substituted benzyl group of the formula: ##STR4## wherein Z is hydrogen, methyl, cyano, ethynyl, or phenyl, and Z is --O-- or --CH 2 --; (b) a benzyl- or phenoxy-substituted furylmethyl group; (c) an imidomethyl group selected from the group consisting of maleimidomethyl, phthalimidomethyl, and tetrahydrophthalimidomethyl; and (d) a benzyl group substituted in at least two ring positions with chloro, methyl, or methylenedioxy group.
Claim 3
Dependent Claim
13 words
