Vilsmeier formylation of 2-(1-phenylhydrazonoethyl)naphtho[2,1-b]furan (2) gave 3-naphtho[2,1-b]furan-2-yl-1-phenyl-1H-pyrazole-4-carbaldehyde (3), which was reacted with C- and N-nucleophiles to afford naphthofuranpyrazol derivatives 4-8. Treatment of 2-[(3-(naphtho[2,1-b]furan-2-yl)-1-phenyl-1H-pyrazol-4-yl)methylene]-malononitrile (4a) with reactants having active hydrogen and Et₃N gave the ...
2-(Pyrrol-1-yl)phenoxyl, aminyl, thiophenoxyl and benzyl radicals 2a-2d, respectively, were generated in the gas-phase under flash vacuum pyrolysis conditions. In all cases except the phenoxyl, cyclisation took place providing acceptable synthetic routes to the fused heterocycles 11, 14 and 15, respectively. Only sigmatropic rearrangement products were isolated, in low yields, from the phenoxyl...
Jednym z głównych pytań w filozofii logiki jest to, czy jedna, wiele logik. Pytanie to doczekało się różnych odpowiedzi, które formułują opozycyjne stanowiska: monizm logiczny contra pluralizm logiczny. Za reprezentatywnego przedstawiciela monizmu uznawany Willard Van Orman Quine, a pluralizmu — Susan Haack. Oba te stanowiska są kontynuowane współcześnie: (m.in. Michael Dummett, Graham Priest, ...
A bstract All the 7 dynamical second order transport coefficients of nonconformal fluids that correspond to Dp-branes with one or more world-volume directions compactified are derived via fluid/gravity correspondence. The conditions considered in this paper include D4-brane 1, 2 3 compact directions, D3-brane 1 as well D2-brane direction compactified. satisfy Haack-Yarom, Romatschke and Kleiner...
