Deprotonation, insertion and isomerisation in the post-functionalisation of tris-pyridyl aluminates†
Abstract
Post-functionalisation of the aluminate anion [EtAl(6-R-2-py)3]− (6-R-2-py = 6-R-2-pyridyl, R = Me or Br) can be accomplished via nucleophilic addition of the pyridyl groups to the electrophilic CO group of aldehydes (RCHO) or by deprotonation of carboxylic acids (RCO2H). NMR spectroscopic and crystallographic studies show how 6-Me-2-py groups can detect chirality and reveal a new aspect of isomerism.
