Metal complexes of a new polyimido sulfur phosphanyl ligand

Abstract

Scheme 1-1: left) Dynamic "on/off"-effect of hemilabile ligands. right) Two examples of hemilabile P,O-and P,N-ligands that are applied in catalytic transformations. Two examples for hemilabile ligands are shown in Scheme 1-1 (right). Silver(I) complexes of the ligand a were demonstrated to be highly effective in promoting the first examples of homogeneous silver catalysed azide-alkyne cycloaddition [As(NR)3] 3arsenite: [AsO3] 3-[P(NR)4] 3phosphate: [PO4] 3-[Se(NR)3] 2selenite: [SeO3] 2-phosphanes in the synthesis (Scheme 1-6). [32] Scheme 1-6: Preparation of [Li{Me2PCH2S(NtBu)2}]2.Based on his results, Meinholz continued the investigation in this field and synthesised successfully a series of metal complexes of diimidosulfinates with a phosphorus side arm, as mentioned previously (Figure 1.2, b and c).
