Abstract

A two-component synthetic procedure for a tetradentate, tripodal organo-fluorine derivative; along with copper(I) and copper(II) analogues is presented. Solid state studies show that the (4TFM-TREN) ligand crystallizes in a monoclinic system with P21/c space group, while the [CuI(4TFM-TREN)][PF6] complex crystallizes in a cubic crystal system with P213 space group. Kinetic studies monitoring the addition of carbon tetrachloride to the copper(I) analogue produced an activation rate constant value of 5 × 10-2 M-1 s-1. UV-Vis spectroscopy results confirmed the ability of compounds presented here to slow down the activation step of atom transfer radical addition reactions employing fast initiators such as carbon tetrachloride. This work addresses a need to develop novel methods that can be used in activation rate constant value calculations for ideal atom transfer radical addition (ATRA) reactions incorporating active copper catalysts and fast initiators.
