Synthesis and solid-state structures of Ph3E-Ga(t-Bu3) Lewis acid-base adducts

Three Lewis acid–base adducts t‐Bu3Ga–EPh3 (E = P 1, As 2, Sb 3) were synthesized by reactions of Ph3E and t‐Bu3Ga and characterized by heteronuclear NMR (1H, 13C (31P)) and IR spectroscopy, elemental analysis and single crystal X‐ray diffraction. Their structural parameters are discussed and compared to similar t‐Bu3Ga adducts. The strength of the donor‐acceptor interactions within 13 was investigated in solution by temperature‐dependent 1H NMR spectroscopy and by quantum chemical calculations.
