Über Reaktionen an Heterocyclen, die eine P – P‐Bindung enthalten

Abstract: Die Pyrolyse der Spiroverbindung 1 a mit einer h3P -h'P-Bindung ergibt unter CarbodiimidAbspaltung 1 ,CDimethyl-2,3-diphenyl-1,4,2,3-diazadiphospholidin-S-on-2-oxid (4). Der molekulare Aufbau wird durch eine Rtintgenstrukturanalyse bestatigt. Die bicyclischen Verbindungen 2a und 3s reagieren mit Schwefel zum P-Oxid-P'-sulfid 5 bzw. P,P-Disulfid 7 ohne Spaltung der P -P-Bindung. Im Gegensatz dazu wird rnit KMnO, in'3a die P -P-Bindung unter Bildung des Oxabicyclo-P,P-dioxids 6 geoffnet, dessen Molekulstrukrur e… Show more

“…For diphosphapentalene derivatives that possess two phosphorus(III) atoms at the bridgehead, four major ring systems III – VI have been structurally characterized (Figure b) . However, studies on their reactivities have been limited to the coordination natures towards transition metals, their oxidation, and reaction with Grignard reagents, and thus still remain unexplored. Considering the importance of phosphorus heterocycles, both the development of unique molecular frameworks and a deep comprehension of their reactivities are essential to broadening their diversity from a fundamental point of view.…”

“…The Lewis acids SbCls and SnCLj react with 3 to give the adducts 6 and 7. The reactions of 3 with the metal carbonyls Fe2(CO)9, Cr(CO)5THF and Cr(CO)4C7Hx lead to the metal complexes [8][9][10]. The compounds were characterized on the basis of 31 P NMR and mass spectra.…”
