Copper(I) complexes of cyclopenta[2,1-b:3,4-b′]dipyridine-5-one and some 2-substituted derivatives
摘要:
The preparation of 2-chloro-cyclopenta[2,1-b:3,3-b']dipyridine-5-one and its reactions with various nucleophiles are reported. The resulting 3-substituted 4,5-diazafluorenones form complexes [CuL2](+) with copper(I) that are characterised by spectroscopy and microanalysis. The preparation of bis-(cyclopenta[2,1-b:3,4-b']dipyridine-5-one-2-yl)ether and its complexes [ML](+) (M = Cu, Ag) which are shown to be dimeric, are described. (C) 2001 Elsevier Science B.V.
