DBU - Not Simply a Strong Base: A One-Pot Synthesis of a Polycyclic Framework Consisting of a Diphosphete Central Unit and Two Units of Doubly Deprotonated DBUTwo condensed five-, six- and seven-membered rings are fused in a spirocyclic fashion with a central four-membered diphosphete ring in 4, which unexpectedly is formed in a simple two-component-one-pot reaction from Cl2P-CH(SiMe3)2 and DBU. The latter is doubly deprotonated and acts as a bridge via C-6 and N-8 to a P-P unit. The polyheterocycle 4 crystallizes in two modifications, whose molecular structures are almost identical.
