CYCLIC AZA-SILA COMPOUNDS AS INSECT REPELLANTS

摘要

The invention relates to aza-sila compounds of Formula (I), useful as insect repellants. wherein, 'A' is selected from the group consisting of branched or unbranched (C I -CI 2) alkyl, branched or unbranched (CI -CI 2) alkynyl; and substituted or unsubstituted 4 to 6 membered acyclic saturated or unsaturated compounds, wherein the substituents are selected from the group consisting of halogen, hydrogen, (CI -C6) alkyl, aryl, arylalkyl and heterocyclic; or ' A' is independently selected from the group consisting of the following moiety: Formula (II) wherein, X and Y are identical or different and independently selected from the group consisting of-C-, -N, -O, and -S; where Rl, R2, R3, and R4 are identical or different and are independently selected from the group consisting of hydrogen, halogen, linear or branched (C1-C6) alkyl, aryl, arylalkyl, hydroxyl, and heterocyclic; and wherein, the halogen is selected from the group consisting of—CI, -I, -Br, and -F. The invention further discloses a process for the preparation of the compounds of Formula (I).
