Some chemical properties of the cyclic bisphosphines 3b and 6, which contain the grouping P-CCl 2 -P, are discussed. Reduction of 3b with R 3 P (R ϭ i-Pr, Ph) gives the dimer 11 of the phosphaalkene 10. 11 may have different structures in solution and in crystalline form. The bridging of 6 with the silylated urea 2 gives the unsymmetrical product 7, which rearranges slowly into 8. Compounds 7 and 8 exhibit unprecedentedly low chemical shifts in the 31 P NMR. The structures of 8 and 11 were established by X-ray analysis and their NMR spectra are discussed. The four-membered Harnstoffverbrückte Bicyclische Bisphosphine mit der Gruppierung P-CCl 2 -P Inhaltsübersicht. Einige chemische Eigenschaften der cyclischen Bisphosphine 3b und 6 mit der Gruppierung P-CCl 2 -P werden diskutiert. Die Reduktion von 3b mit R 3 P (R ϭ i-Pr, Ph) führt zum Dimer 11 des Phosphaalkens 10. Die Struktur von 11 in Lösung scheint von der im Festzustand verschieden zu sein. Die Verbrükkung der Phosphoratome von 6 mit N,NЈ-Dimethyl-N,NЈbis(trimethyl-silyl)harnstoff ergibt das unsymmetrische Produkt 7, das sich langsam in 8 umlagert. Die Verbindungen 7 und 8 fallen durch ungewöhnlich niedrige δ( 31 P)-Werte auf. Die Strukturen von 8 und
