Organic and Biological Chemistry: Nuclear Magnetic Resonance Investigation of Secondary Valence Forces. I. Intramolecular π Coordination in Aralkylmercury Compounds

Abstract

A general approach to the study of weak donor-acceptor interactions is described, based on conformational analysis of a flexible intramolecular model by nuclear magnetic resonance spectroscopy. The major feature of this model is a centrally located asymmetric center, which allows strong magnetic nonequivalence in flanking methylene groups to develop when intramolecular coordination is present. Applications of this approach to a series of λ-arylpropylmercury compounds reveals the that π electrons of a benzene ring are involved in coordinate bonding with the mercury atom. © 1968, American Chemical Society.
