New types of polyfunctional molecules formed by Co2+/3+ and Zn2+ ions with various diamines - biogenic 1,4-diaminobutane (dab, putrescine) and 1,1′-binaphthyl-2,2′-diamine (dabn) - have been obtained. The structure of the compounds was determined by single crystal X-ray diffraction analysis. Dab in the binuclear complex [Zn2(piv)2(dab)2(Hdab)2]·4piv·2H2O (1) plays the role of a bridging ligand. The H-binding in 1 promotes the formation of a supramolecular layer which, according to STA data, predetermines the thermal stability up to 100 °C. In the mononuclear complex of cobalt(III), [CoIII(piv)2(dab)2]+Cl? (2), dab is chelated with the metal center. Replacement of dab with dabn leads to solely chelate coordination in complexes of cobalt(II), [Co3(OH)(piv)5(dabn)2]·0.5MeCN (3), and zinc, [Zn(dabn)2(NO3)(MeCN)]·2NO3·0.5MeCN (4).

Kinetic, spectroscopic, crystallographic, and computational studies probing a Pd-catalyzed C-H arylation reaction reveal that mono-oxidation of the bis-phosphine ligand is critical for the formation of the active catalyst. The bis-phosphine mono-oxide is

The cleavage of α-ketoepoxycarbinyl radicals has been investigated for six substrates using two methods of radical formation.Products resulting from carbon-oxygen bond cleavage were observed in each case, but vinyl ethers derived from epoxide carbon-carbon cleavage were isolated in one case.
