Abstract

Abstract : A tailor-made synthetic procedure was devised to produce a four-palladium supramolecular architecture capable of hosting two A-frame moieties. Abstract : Palladacycles of the type [Pd2 (Ph2 PCH2 PPh2 - P, P )2 ( C, N : C, N )] ( C, N : C, N = bis( N -2, 3, 4-trimethoxybenzylidene)-4, 4′-sulfonyldianiline or -4, 4′-oxydianiline) can undergo a spontaneous slow chelate-to-bridging diphosphane coordination shift in solution. Following this strategy a tailor-made synthetic procedure was devised that culminates in isolation of double A-frame tetranuclear palladium complexes.
