Reactivity of intramolecularly coordinated aluminum compounds to R3EOH (E = Sn, Si). Remarkable migration of N,C,N and O,C,O pincer ligands

Abstract

The reaction of organoaluminum compounds containing O,C,O or N,C,N chelating (so called pincer) ligands [2,6-(YCH2)(2)C6H3]-(AlBu2)-Bu-i (Y = MeO 1, (BuO)-Bu-t 2, Me2N 3) with R3SnOH (R = Ph or Me) gives tetraorganotin complexes [2,6-(YCH2)(2)C6H3]SnR3 (
