Versatile coordination of a reactive P,N-ligand toward boron, aluminum and gallium and interconversion reactivity.
The synthesis and reactivity of the first Group 13 complexes bearing a dearomatized phosphino-amido ligand are reported, i.e. alane AlEt2(L) , gallane GaCl2(L) and borane B(Cl)(Ph)(L) . The three complexes react very differently with Group 13 trihalogenides, providing access to zwitterionic anti-·GaCl3 and the unique bis(metalloid) ·BCl2, with the boron center part of a highly unusual anionic four-membered ring (charge on C) and Ga bound to P. The coordination chemistry and the various transformations are supported by DFT calculations, X-ray crystallography and multinuclear NMR spectroscopic data.
