Abstract

Three-coordinate alkylaluminum sites were developed on a catechol-containing porous organic polymer support (CatPOP A₂B₁). The CatPOP-based alkylaluminum sites were characterized by solid-state attenuated total reflectance IR spectroscopy, ¹H and ²⁷Al magic-angle-spinning NMR spectroscopy, pair-distribution function X-ray absorption spectroscopy, and elemental analysis. The low-coordinate organoaluminum sites can hydrogenate and isomerize a range of mono- and disubstituted alkenes and alkynes under mild conditions (75-100 °C, 5-14 bar H₂, 20 h). Results of experimental and computational mechanistic investigations suggest a heterolytic mechanism for the observed hydrogenation-isomerization activity.
