Structural Analysis of Transition Metal β-X Substituent Interactions. Toward the Use of Soft Computing Methods for Catalyst Modeling

Abstract
Fuzzy logic and neural network techniques are used to classify intramolecular interactions between transition metals (M) and β-X substituents in the following structural motif (LnMCα(A1)(A2)-Cβ(B1)(B2)X). These interactions are relevant to the direct polymerization of functionalized olefins by Ziegler−Natta (ZN) catalysis. The efficiency and effectiveness of different soft computing techniques are compared. These methods give not only encouraging results with respect to general data mining issues but also insight into the factors that effect interactions between transition metals and β-X substituents.
