Four novel bidentate phosphine-Pd complexes coordinated by NiN2S2 metallodithiolate ligands were synthesized and characterized, including XRD analysis; these redox-active complexes are stable in air, and they survive column chromatography on silica gel. The Ni-Pd bimetallic complexes are demonstrated to be precatalyst for Suzuki-Miyaura cross-coupling reactions. The best of these has an overall yield of over 99% under only 1% catalyst loading. The role of NiN2S2 as a stabilizing bidentate ligand, that is also oxidizable may account for its efficacy in the support of the catalysis.

The present invention provides, among other things, a novel class of cationic lipid compounds (e.g., cationic lipids having a structure according to Formula (I)) forin vivodelivery of therapeutic agents, such as nucleic acids. It is contemplated that these compounds are capable of highly effectivein vivodelivery while maintaining a favorable toxicity profile.

The homohexanuclear complexes [Ni2Ni(L1)}4](BF4)4·MeCN, 1, [Pd2Pd(L2)}4](BF4)4, 2, and the heteropentanuclear aggregate [Cu2Ni(L3)}3](PF6)2, 3, all adopt a ‘pinwheel’ type structural motif via thiolate bridging between square-planar Ni(II) or Pd(II) and between trigonal planar Cu(I) centres, respectively.
