Abstract: The dithiocarbonato metal complexes M(κ2S,S-S2CO)(κ2P,P-dppf) {M= Ni, Pd, Pt; dppf= bis(diphenylphosphino)ferrocene} are obtained from the reaction of the metal(II) complexes [M(κ2S,S-S2COEt)2] with the dppf ligand or from the chloride substitution of M(κ2P,P-dppf)Cl2 by the O-ethyldithiocabonato anion. These complexes are produced by C-O bond cleavage by the O-ethyldithiocarbonato anion present in solution. These new complexes have been characterized by UV-Vis, NMR, IR spectroscopy and elemental analysis. The structures of the three complexes were further confirmed by single-crystal X-ray diffraction analysis.

Compound sodium N-(ethoxythioxomethyl)-β-alaninate (sodium 3-(ethoxycarbonothioyl)propanoate) was synthesized and characterized by IR, 1HNMR, ESI-HRMS and single crystalX-ray diffraction. Single crystalX-ray diffraction analysis showed that the title compound crystallized in the triclinic space group P-1 with cell parameters a = 10.142 (2) A, b = 13.738 (3) A, c = 15.751 (3) A, α= 72.937 (2)°, β = 78.694 (2)°, γ = 89.999 (2)°, V = 2053.4 (7) A3, Dc = 1.464 g cm-3, Z = 2. In the extended structure of sodium N-(ethoxythioxomethyl)-β-alaninate-water (4/6), (NaL)4· 6H2O [L = CH3CH2OC(S)NHCH2CH 2COO], ligands (Ls) are stabilized by intermolecular O-H···O, N-H···O, C- H···O and weak O-H···S and C-H···S linkages, which further consolidate the crystal packing, making the ligand chains stacked along [0-1 1], and intramolecular O-H···S hydrogen bond is also observed. Each Na atom is surrounded with six O atoms, forming an octahedron and mutually bonded as tetramers. These tetramers are linked through O atom bridges from water molecules, extending as layers in the ab plane. In addition, synthesis of β-alanyl dipeptides was developed with particular focus on the preparation of L-carnosine. Springer Science+Business Media New York 2012.
New radical reactions of S-alkoxycarbonyl xanthates. Total synthesis of (±)-cinnamolide and (±)-methylenolactocin

Irradiation with visible light of S-alkoxycarbonyl xanthates derived from various alcohols gives rise to alkoxycarbonyl radicals with bifurcate reactivity: loss of carbon dioxide leads to deoxygenated derivatives (i.e. alkyl xanthates) whereas intramolecular addition to a suitably located double bond produces lactones; these new reactions were applied to the total synthesis of (±)-cinnamolide and (±)-methylenolactocin.
