Abstract
The oligotrimerization of hexamethylene diisocyanate by tributylin oxide (TBTO), Zr(OBu)4, Ti(OBu)4 and Pb-naphthenate was studied. For mild reaction conditions, i.e. weak catalyst (TBTO), low catalyst concentration and temperature, the reaction gave selectively the cyclic trimer (I) and not higher oligomers.
