Abstract
Abstract This invention relates to novel compounds of the formula ##STR1## wherein R 1 is lower alkenyl or lower alkynyl; R 2 is lower alkenyl, lower alkynyl or cycloalkyl; R 3 is hydrogen; R 4 is alkyl, cycloalkyl or lower alkoxycarbonylalkyl or R 2 and R 3 are joined to form dimethyleneoxy (i.e. --CH 2 OCH 2 --) or R 3 and R 4 taken together with the nitrogen to which they are attached, form a 5- to 6- membered heterocyclic ring, compositions containing said compounds and a method of employing said compounds as arthropod repellents.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A method for repelling arthropods which comprises applying to an appropriate surface an effective repellent amount of the compound of the formula: ##STR17## wherein R 1 is alkenyl or alkynyl; R 2 is alkenyl, alkynyl or cycloalkyl, or phenyl lower alkyl, R 3 is hydrogen and R 4 is alkyl, alkoxycarbonylakyl or cycloalkyl or R 2 and R 3 are joined to form a dimethyleneoxy or R 2 and R 4 , taken together with the nitrogen atom to which they are attached, may be joined to form a 5- to 7-membered heterocyclic ring.
Claim 2
Independent Claim
94 words
A method for repelling arthropods which comprises applying to an appropriate surface an effective repellent amount of the compound of the formula: ##STR17## wherein R 1 is alkenyl or alkynyl; R 2 is alkenyl, alkynyl or cycloalkyl, or phenyl lower alkyl, R 3 is hydrogen and R 4 is alkyl, alkoxycarbonylakyl or cycloalkyl or R 2 and R 3 are joined to form a dimethyleneoxy or R 2 and R 4 , taken together with the nitrogen atom to which they are attached, may be joined to form a 5- to 7-membered heterocyclic ring.
Claim 3
Independent Claim
89 words
A method for repelling arthropods which comprises applying to an appropriate surface an effective repellent amount of a compound of the formula ##STR18## wherein R 5 is allyl, 2-methylallyl or 2-propynyl; R 6 is allyl, 2-methylallyl or cyclohexyl; R 7 is hydrogen; R 8 is lower alkyl, lower alkoxycarbonylmethyl or cycloalkyl of 5 to 7 carbon atoms or R 6 and R 7 are joined to form dimethyleneoxy or R 7 and R 8 taken together with the nitrogen to which they are attached are joined to form pyrrolidyl.
Claim 4
Independent Claim
89 words
A method for repelling arthropods which comprises applying to an appropriate surface an effective repellent amount of a compound of the formula ##STR18## wherein R 5 is allyl, 2-methylallyl or 2-propynyl; R 6 is allyl, 2-methylallyl or cyclohexyl; R 7 is hydrogen; R 8 is lower alkyl, lower alkoxycarbonylmethyl or cycloalkyl of 5 to 7 carbon atoms or R 6 and R 7 are joined to form dimethyleneoxy or R 7 and R 8 taken together with the nitrogen to which they are attached are joined to form pyrrolidyl.
Claim 5
Dependent Claim
11 words
The method of claim 2 wherein the repellent comprises N-allyl N-cyclohexyl-N'-methylurea.
Claim 6
Dependent Claim
10 words
The method of claim 2 wherein the repellent comprises N-allyl-N-cyclohexyl-N'-propylurea.
Claim 7
Dependent Claim
10 words
The method of claim 2 wherein the repellent comprises N-allyl-N-cyclohexyl-N'-butylurea.
Claim 8
Dependent Claim
10 words
The method of claim 2 wherein the repellent comprises N-allyl-N-cyclohexyl-N'-carboethoxymethylurea.
