Diisocyanates 1 are important building blocks in polymer chemistry [1]. In the manufacture of elastomers, plastics and coatings they react with polyhydroxylic components to give polyurethanes and with polyamines to give polyureas. To meet the requirements for advanced materials it is necessary to l
