Chelated flavonol co-ordination in flavonolatobis(triphenylphosphine)copper(I)
Abstract
3-Hydroxyflavone co-ordinates to copper(I) by its 3-hydroxy and 4-carbonyl groups together with two triphenylphosphines to form a distorted tetrahedron with a high electron delocalization on the flavonolate ligand, as shown by an X-ray crystal structure determination.
