Abstract

original image

Side on: Elemental sulfur (S8) reacts with a tridentate chelate (MePY2)math image copper(I) compound, generating a side on μ-η22-disulfido bridged complex [{CuII(MePY2)math image}2(S22−)]2+ (see structure: yellow S, green Cu, blue N, gray C); its reactivity towards PPh3, RNC, CO, O2, PhCH2Br, and a tetradentate chelating ligand are described.
