Nine different β-thioxoketones of general formula R(1)C(=O)CH2C(=S)R(2) (R(1) = C6H5, R(2) = C6H5L1; R(1) = C6H5, R(2) = p-CF3C6H4L2; R(1) = p-MeOC6H4, R(2) = C6H5L3; R(1) = p-MeOC6H4, R(2) = p-CF3C6H4L4; R(1) = C5H4N, R(2) = C6H5L5; R(1) = p-IC6H4, R(2) = C6H5L6; R(1) = C6H5, R(2) = p-IC6H4L7; R(1) = C6H5, R(2) = C10H7L8 and R(1) = CH3, R(2) = C6H5L9) and(More)
Reaction of Bi(O(t)Bu)3 with aspirin (acetylsalicylic acid = aspH) in dry toluene results in the bismuth(III) complex, [Bi(O2C(C6H4)OAc)3]∞ 1 (O2C(C6H4)OAc = asp), minimum inhibitory concentration (MIC) against Helicobacter pylori ≥ 6.25 μg mL(-1), while the inclusion of a stoichiometric equivalent of KO(t)Bu leads to crystals of the bismuthate salt(More)
Performed with a desire to advance knowledge of the structures and mechanisms governing alkali-metal-mediated zincation, this study monitors the reaction between the TMP-dialkylzincate reagent [(TMEDA)Na(TMP)((t)Bu)Zn((t)Bu)] 1 and trifluoromethyl benzene C(6)H(5)CF(3) 2. A complicated mixture of products is observed at room temperature. X-ray(More)
Reaction of BiPh3 or Bi(O(t)Bu)3 with benzohydroxamic acid (H2-BHA) results in formation of novel mono- and di-anionic hydroxamato complexes; [Bi2(BHA)3]∞ 1, [Bi(H-BHA)3] 2, [Bi(BHA)(H-BHA)] 3, all of which display nM activity against Helicobacter pylori. Subsequent dissolution of [Bi2(BHA)3]∞ in DMSO/toluene results in hydrolysis to the first structurally(More)
Comparing the reactivity of the related lithium zincates [(THF)LiZn(TMP)(t)Bu(2)] (1) and [(PMDETA)LiZn(t)Bu(3)] (2) towards pyrazine discloses two new bimetallic approaches for the selective 2,5-dideprotonation and room temperature C-H alkylation of this sensitive heterocycle.
Subjecting furan to sodium-mediated magnesiation via the new heteroleptic alkyl-amido reagent [(TMEDA).Na(CH(2)SiMe(3))(TMP)Mg(TMP)] produces the remarkable dodecasodium-hexamagnesium molecule [{(TMEDA)(3)Na(6)Mg(3)(CH(2)SiMe(3))(2,5-C(4)H(2)O)(3)(2-C(4)H(3)O)(5)}(2)], built upon a bridge network of 10 monodeprotonated and 6 twofold-deprotonated furan(More)
Metallation of two analogous N- and P-allyl molecules Ph2NCH2CHCH2 and Ph2PCH2CHCH2 with nBuLi have shown contrasting reactivities based on the choice of Lewis donor. With metallation of the alpha carbon atom was achieved regardless of the Lewis donor used while in comparison metallation of showed an unexpected donor denticity dependence with P-C bond(More)
With the aim of introducing the diisopropylamide [NiPr(2)](-) ligand to alkali-metal-mediated manganation (AMMMn) chemistry, the temperature-dependent reactions of a 1:1:3 mixture of butylsodium, bis(trimethylsilylmethyl)manganese(II), and diisopropylamine with ferrocene in hexane/toluene have been investigated. Performed at reflux temperature, the reaction(More)

Extending the recently introduced concept of "alkali-metal-mediated manganation" to functionalised arenes, the heteroleptic sodium manganate reagent [(tmeda)Na(tmp)(R)Mn(tmp)] (1; TMEDA=N,N,N',N'-tetramethylethylenediamine, TMP=2,2,6,6-tetramethylpiperidide, R=CH2SiMe3) has been treated with anisole or N,N-diisopropylbenzamide in a 1:1 stoichiometry in(More)
