Dialkylgallium Complexes with Alkoxide and Aryloxide Ligands Possessing N‑Heterocyclic Carbene Functionalities: Synthesis and Structure
Methods for the synthesis
of dialkylgalium compounds with alkoxide
or aryloxide ligands possessing N-heterocyclic carbene functionalities
have been established. As a result, the synthesis of a series of dialkylgallium
complexes Me<sub>2</sub>Ga(O,C) (<b>1</b>, <b>3</b>–<b>5</b>), and Me<sub>2</sub>Ga(O,C)·Me<sub>3</sub>Ga (<b>2</b>, <b>6</b>) is described, where (O,C) represents an
alkoxide or aryloxide monoanionic chelate ligand with an N-heterocyclic
carbene functionality. All complexes have been fully characterized
using spectroscopic and X-ray techniques. The presence of a strongly
basic NHC functionality in alkoxide or aryloxide ligands resulted
in the formation of monomeric Me<sub>2</sub>Ga(O,C) species. The reaction
of those complexes with the Lewis acid Me<sub>3</sub>Ga leads to Me<sub>2</sub>Ga(O,C)·Me<sub>3</sub>Ga adducts (<b>2</b> and <b>6</b>) with a strong Me<sub>3</sub>Ga–O dative bond. The
effect of (O,C) ligands with various steric and electronic properties
on the structure of obtained Me<sub>2</sub>Ga(O,C) and Me<sub>2</sub>Ga(O,C)·Me<sub>3</sub>Ga has been discussed on the basis of
spectroscopic data. Finally, the bond valence vector model has been
used to estimate the effect of a chelating (O,C) ligand on strains
in complexes <b>1</b>–<b>6</b> on the basis of
X-ray data
