Specific insertion reactions of a germylene, stannylene and plumbylene into the unique P-P bond of the hexaphospha-pentaprismane cage, P6C4Bu4: Crystal and molecular structures of P6C4Bu4ER2 (E = Ge, Sn, R = N(SiMe3)2; E = Pb, R = (C6H3(NMe2)2 -2,6).

摘要

Treatment of the cage compound (P6C4Bu4)-Bu-t with M{N(SiMe3)(2)}(2) (M = Ge or Sn) or Pb(C6H3(NMe2)(2-)2,6) at room temperature results in their specific insertion into the P-P bond connecting the two 5-membered (P3C2Bu2)-Bu-t rings. The products were fully characterised by multinuclear NMR spectroscopy and single crystal X-ray diffraction studies.
