Synthesis and stereochemistry of novel triarylmesitylenes; Bases for rigid tridentate ligands.
01 January 1987
The syntheses of 2,4,6-tris(1-naphthyl), (2-methylphenyl), and (4-dibenzofuranyl)mesitylene are described, and evidence for their existence as stereoisomeric mixtures is presented. The DeltaG for interconversion of the syn and anti dibenzofuranyl compounds is 30 kcal/mol at 100C. The syn isomers are expected to serve as frameworks for the construction of rigid tridentate ligands.
