(tBuP)4CO, the First Cyclic Phospha-Urea Derivative - Synthesis and Reaction-Pathways in the System tert-Butylbis(trimethylsilyl)phosphane/Phosgene

The reaction of tert-butylbis(trimethylsilyl)phosphane with phosgene leads to elimination of trimethylchlorosilane and CO via several detectable intermediates with phospha-alkene structure and formation of the first cyclic phospha-urea derivative, 1,2,3,4-tetra-tert-butyl-1,2,3,4-tetraphospholan-5-one (7).
