Access to Bis-Silylene-Stabilized Group 13 Cations

Abstract

Herein, we report the isolation of pyridine moiety-functionalized SiNSi pincer-based bis-silylene ligand (1) and its reactivity toward various halide precursors (X = Br and I) of group 13 elements (M = Al, Ga, and In). This gave us straightforward access to the SiNSi pincer-coordinated group 13 cations (2–7). These complexes are duly characterized by single-crystal X-ray diffraction studies, multinuclear magnetic resonance spectroscopy (1H, 13C, and 29Si), and high-resolution mass spectrometry techniques. Their electronic properties were further analyzed with the help of quantum chemical calculations.
