	abstract = {A series of dichloride complexes of titanium and zirconium with amidate and ureate ancillary ligands have been prepared, Three examples of bis(amidate)dichlorotitanium and zirconium complexes were effectively synthesized through salt metathesis with metal tetrachloride as starting materials. Optimum results were achieved using sodium amidate salts formed from sodium bis(trimethylsilyl)amide and neutral amide proligands, while other methods were ineffective. Use of electron-donating ureate ligands in lieu of amidates enables preparation through alternate routes. Protonolysis of Ti(NMe2)(2)Cl-2 and Zr(NMe2)(2)Cl-2(dme) with urea proligands leads to dichlorobis(ureate) complexes in good yield. Using a tethered bis(ureate) ligand eliminates the fluxional behaviour and coordination isomerism observed for both bis(amidate) and bis(ureate) zirconium complexes. ((C) Wiley-VCH Verlag GmbH \& Co.

	abstract = {We have been interested in merging synthetic nucleotide chemistry with combinatorial selection of DNAzymes to deliver a more complete (and complex) chemical complement to the catalytic repertoire of nucleic acids. Thus we ask, what do modified dNTPs really bring to nucleic acids in terms of an increased repertoire? In asking this question, we have looked first at conditions, and more recently for reaction classes where nucleic acids are found to be catalytically inefficient, deficient, or at least to date, seemingly incapable of certain functions. A case of this is M2+-independent ribophosphodiester hydrolysis at physiological pH and low ionic strength where nucleic acids exhibit especially low rate constants for self-cleavage and seem to be incapable of turnover.},

	abstract = {A family of nitrile complexes has been prepared by reaction of Ru2Cl4(PP)(2) Or RuCl2(PP)(PPh3) (PP = Ph2P(CH2)(4)PPh2 (dppb), Ph2PCH2CHOCMe2OCHCH2PPh2 (diop), 2,2{\textquoteright}-bis(diphenylphosphino)-1, 1{\textquoteright}-binaphthyl (binap)) with MeCN or PhCN, the product formed depending strongly on the reaction conditions. At high nitrile concentrations, the principal species present is RuCl(PP)(RCN)(3)X-+(-) (X = Cl); the cation can generally be isolated (as the PF6 salt) by abstraction of the chloride counterion with NH4PF6. Use of 2 equiv of NH4PF6 generates Ru(PP)(RCN)(4)(2+)(PF6-)(2) (PP = dppb). In the absence of a halide-abstracting agent, addition of hexanes or diethyl ether precipitates neutral RuCl2(PP)(RCN)(2) species, which undergo further loss of nitrile in the solid state (R = Me) or in solution (R = Me, Ph). Redissolution of the neutral species in chlorocarbon solvents gives Ru2Cl3(PP)(2)(RCN)(2)X-+(-) (X = Cl) and, in benzene, Ru2Cl4(PP)(2)(RCN). The dinuclear cation (X = PF6) is also accessible by reaction of RuCl(PP)(RCN)(3)+PF6- with CH2Cl2 or CDCl3, while the mononitrile can be obtained directly by reaction of Ru2Cl4(PP)(2) or RuCl2(PP)(PPh3) with small amounts of nitrile in benzene.},
