ABSTRACT:
Copper(I)-diamine-chloride complexes are prepared by the reaction of cuprous chloride with a diamine such as N,N'-di-t-butylethylenediamine. Said complexes are reacted with phenoxides such as potassium 2,6-xylenoxide to produce the corresponding copper(I)-diamine-phenoxide complexes, which are useful for the preparation of polyphenylene oxides by oxidative coupling of various phenols such as 2,6-xylenol.
