The reaction of N,N′-dimethyl-N,N′-bis(trimethylsilyl)urea with PCl 3  leads to the bicyclic compound OP 2 [MeNCONMe] 2  (3) with a direct phosphorus-phosphorus bond and to the bicycle MeNP 2 [MeNCONMe] 2  (4). 3 reacts with tetrachloro-o-benzoquinone (TOB) to yield the spirocycle Ce 6 Cl 4 tMeNCONMe] 2 P 2 O (5) with a λ 4 P-λ 5 P-bond. The Lewis acids SbCl 5  and SnCL 4  react with 3 to give the adducts 6 and 7. The reactions of 3 with the metal carbonyls Fe 2 (CO) 9 , Cr(CO) 5 THF and Cr(CO) 4 C 7 H 8  lead to the metal complexes 8-10. The compounds were characterized on the basis of  31 P NMR and mass spectra.
