Abstract
AbstractBased on a semiflexible trisilacyclohexane framework a series of directed, tridentate Lewis acids were synthesized by hydrosilylation using various (chloro)methylsilanes. The axial alignment of the three electron deficient functions in one spatial direction allows creating poly‐Lewis acids with chalice‐like cavities. The directed, tridentate poly‐Lewis acids were obtained in quantitative yields and characterized by multinuclear NMR spectroscopy, CHN analysis and X‐ray diffraction experiments. The Lewis acidity of the introduced silicon functions was quantified and classified using the Gutmann‐Beckett method.
