Oxidative oligomerisation of 2-naphthol by cis-bis(glycinato)copper(II)

The reaction of 2-naphthol with tert-butylhydroperoxide by cis-bis(glycinat o)copper(II) oligomerises 2-naphthol. One of the isolated tetramer A contai ns a tert-butyloxy group. Similar reaction of 2-naphthol with hydrogen pero xide in the presence of cis-bis(glycinato) copper(II) oligomerises 2-naphth ol gives tetramer through hydroxylative oligomerisation. The oligomers are bound to ore-bridged copper cores to give B and C. These oligomers exhibit thermal sensing property. The oligomer (B) converts benzamide to benzoic ac id, as well as catalyses oxidation of aromatic aldehydes such as benzaldehy de to corresponding acids. (C) 2001 Elsevier Science B.V.
