The preparations and properties of a number of ortho-hydroxyoximes are described. Several of the compounds have not previously been characterised. The kinetics of extraction of copper(II) from acidic perchlorate media into toluene solutions of these reagents has been investigated by means of a single drop technique. A mechanism consistent with the rate data is presented in which the importance of interfacial concentration terms is emphasised. Variations in the rates of extraction observed for compounds of different structures are rationalised in terms of the mechanism proposed.
