• Palladium-catalysed direct diarylations of pyrazoles with aryl bromides: a one step access to 4,5-diarylpyrazoles

  日期：2014.3

  The palladium-catalysed direct arylation of pyrazoles with aryl halides, using PdCl(C3H5)(dppb)/KOAc catalyst, reveals a similar reactivity of C4 and C5 CH bonds of pyrazoles, whereas the C3 CH bond is almost unreactive, and gives access in one step to a variety of 4,5-diarylpyrazoles. This CH bond functionalisation reaction tolerates a variety of substituents on the aryl bromide such as nitro, cyano

  使用PdCl（C 3 H 5）（dppb）/ KOAc催化剂，钯催化吡唑与芳基卤化物的直接芳基化反应显示出吡唑的C4和C5 C H键具有相似的反应性，而C3 C H键几乎不具有反应性，并一步一步即可获得各种4,5-二芳基吡唑类化合物。该C H键官能化反应容许芳基溴化物上的各种取代基，例如硝基，氰基，甲酰基，丙酰基，酯，氯，氟或三氟甲基。

• Alkali-metal mediated zincation of N-heterocyclic substrates using the lithium zincate complex, (THF)Li(TMP)Zn(tBu)2 and applications in in situ cross coupling reactions

  This study investigates the ability of the mixed-metal reagent [Li(TMP)Zn(tBu)(2)] 1 to promote direct Zn-H exchange reactions (zincations) of a wide range of N-heterocyclic molecules. The generated metallated intermediates from these reactions are intercepted with I-2 and some of them are also employed as precursors in Pd-catalysed Negishi cross-coupling applications. A comparison with recent precedents in metallation chemistry reveals that for some of these heterocycles, 1 allows improved conversions, under milder conditions and in certain cases, even gives unique regioselectivities.
