Cyclo-oligomerization of isocyanates with Na(PH(2)) or Na(OCP) as “P(–)” anion sources

We show that the 2-phosphaethynolate anion, OCP(–), is a simple and efficient catalyst for the cyclotrimerization of isocyanates. This process proceeds step-wise and involves five-membered heterocycles, namely 1,4,2-diazaphospholidine-3,5-dionide anions and spiro-phosphoranides as detectable interme...
