Synthesis of Tris(N,N-dimethylthiocarbamoyl)-1,1,1-tris-(methylaminomethyl)ethane and Its Application as Ligand for Pauson–Khand Reaction

Abstract

Tris(N,N-dimethylthiocarbamoyl)-1,1,1-tris(methylaminomethyl)ethane ligand was prepared from very cheap and commercially availably tris-1,1,1-(hydroxymethyl)ethane in five steps and applied as ligand in 1:1 coordination to cobalt in a catalytic Pauson–Khand reaction with Co2(CO)8 as catalyst.
