Title

CONVENIENT SYNTHESIS OF NEW 1,10-PHENANTHROLINE LIGANDS AND THE DEPENDENCE OF THEIR CONFORMATIONS ON COMPLEXATION

Introduction

Derivatives of phenanthroline are widely used in analytical and inorganic chemistry as ligands for complexation of heavy metals. In particular, they bind cations of heavy metals in the processes of the industrial wastewater purification.

Purpose

Development of a new synthetic methodology for phenanthroline derivatives.

Method

We suggested a new simple procedure for the preparation of substituted phenanthrolines: a treatment of the commercially available epoxide (1) with various thiols in a presence of a base.

Results

A broad series of novel aryl(alkyl)sulfanyl-substituted 5,6-dihydro-1,10- phenanthrolines (2) and 1,10-phenanthrolines (3) has been prepared. Conformational changes in ligands 2 upon complexation with metal ions were monitored by 1H NMR.

Significance

We developed a new approach to preparation of phenanthrolines, which allows attachment of various functional groups for modification of their properties. In particular, these groups allow a use of the products as building blocks in synthesis of versatile ligands and in functionalization of surfaces.
