Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insecticidal and acaricidal compounds are limited in their effectiveness and diversity, necessitating the development of new 2,2-dihalocyclopropyl compounds with enhanced biological activity for protecting plants against insects and acarines.
Innovation Solution
The introduction of novel 2,2-dihalocyclopropyl compounds, as defined by Formula (I), which include various substituents and functional groups, offering improved pesticidal activity against insects and acarines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing insecticidal and acaricidal compounds are used, then plant protection against insects and acarines is provided, but the effectiveness and diversity of protection are limited
Solution Approach 1:
The patent applies parameter changes by systematically varying the chemical structure of 2,2-dihalocyclopropyl compounds through different substituents (R1-R6), halogen types (F, Cl, Br, I), and molecular configurations to create a diverse series of compounds with enhanced and varied pesticidal activities against different insect and acarine pests
2Adaptability or versatility
If novel 2,2-dihalocyclopropyl compounds with various substituents are introduced, then pesticidal activity and diversity are improved, but compound complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex molecule into distinct functional segments (cyclopropyl core with 2,2-dihalogen substitution, and six variable substituent positions R1-R6), allowing systematic modification of individual segments to achieve diverse pesticidal activities while maintaining a manageable structural framework
Solution Approach 2:
The patent applies universality by designing a core 2,2-dihalocyclopropyl structure that serves as a universal scaffold for multiple pesticidal applications, where the same basic structure can be adapted through substituent variation to target different insect and acarine pests, providing multi-functional protection
