  • Title: Wire-like PtC[triple bond]CC[triple bond]CC[triple bond]CC[triple bond]CPt moieties surrounded by double-helical "insulation": new motifs featuring P(CH2)20P and P(CH2)4O(CH2)2O(CH2)4P linkages.

    Journal: Dalton Trans; 2006 Jun 28; (24):2929-33. PubMed ID: 16770450.
    Abstract:
    Ring-closing alkene metatheses of trans,trans-(C6F5)(Ph2P-Z-CH=CH2)2Pt(C[triple bond]C)4Pt(Ph2P-Z-CH=CH2)2(C6F5) (Z = (CH2)9, (CH2)4O(CH2)2), followed by hydrogenation, give the title compounds; the former exhibits an exceptionally twisted conformation, and the latter establishes that functional groups can be incorporated into the flexible sp3 chain.
