Diphosphine-phosphenium coordination complexes representing monocations with pendant donors and ligand tethered dications

Homoatomic P-P coordinate bonding is exploited to prepare the first examples of triphosphorus monocations and tetraphosphorus dications using dimethylphosphenium or diphenylphosphenium Lewis acceptors with diphosphinomethane, diphosphinoethane, diphosphinohexane, or diphosphinobenzene ligands. Solid-state structures and spectroscopic characterization data for complexes involving bis(diphenylphosphino)methane ligands show coordination of only one donor site of the diphosphine ligand in the monocations, and chelate complexation is not observed. Tetraphosphorus dications are observed with longer diphosphines, in which the ligand tethers two phosphenium acceptors. The structural preferences between monocations with pendant phosphines and tethered dications are dependent on intramolecular steric interactions and the flexibility of the tether.

The synthesis and structural characterization of linear and macrocyclic bis(dinitrosyliron) complexes supported by bis(phosphine) bridging ligands

Reactions involving Fe(NO)2(CO)2 and the bis(phosphine) ligands bis(diphenylphosphino)methane (DPPM), bis(diphenylphosphino)acetylene (DPPA), 1,6-bis(diphenylphosphino)hexane (DPPH), and 1,4-bis(diphenylphosphino)-benzene (DPPB) have been examined. From these reactions, the mononuclear complex, Fe(kappa1-DPPM)(NO) 2(CO) 3, linear dinuclear species of the type Fe2(mu -L)(NO)4(CO)2 (L = Ph2PCH2PPh 2 4, Ph2PC?CPPh2 5, Ph 2PCH2(CH3)4CH2PPh 2 6, and Ph2P(p-C6H4)PPh 2 7), and macrocyclic dinuclear species of the type Fe 2(mu-L)2(NO)4 (L = Ph2PCH 2PPh2 8 and Ph2PC?CPPh2 9) were isolated and spectroscopically characterized.

Efficient One-Pot Synthesis of 2,4-Disubstituted Thiazoles and Dimeric Thiazoles Directly from Acyl Chlorides and beta-Azido Disulfides

A simple and effective one-pot cascade procedure to provide 2,4-disubstituted thiazoles and symmetrical dimeric thiazoles directly from commercially available acid chlorides and beta-azido disulfides in moderate to high yields is described. This cascade transformation consists of disulfide cleavage, thiocarbonylation, phosphine-promoted intramolecular Staudinger/aza-Wittig reaction and dehydrogenation to form the corresponding thiazoles. The application of our methodology is demonstrated by the concise two-step synthesis of anticancer agent SMART and its O-linked dimer in 64% and 46% overall yields, respectively. This directed cascade reaction could be easily handled and scaled up under mild conditions, enabling the construction of focused thiazole derivatives for further pharmacological evaluation.
