  polysubstituted quinolines from o-vinyl anilines and aldehydes. The reaction proceeds in a cascade manner through condensation, electrocyclization and dehydrogenation, and gives access to a wide range of quinolines with alkyl and/or aryl substituents as demonstrated with 40 examples. The metal-free catalytic procedure allows a heterogeneous protocol for the synthesis of various polysubstituted quinolines. The

  The reactivity of Pd–PEPPSI (Pyridine, Enhanced, Precatalyst, Preparation, Stabilization, and Initiation) precatalysts in the Stille–Migita cross‐coupling reaction between heteroaryl stannanes and aryl or heteroaryl halides was evaluated. In general, Pd–PEPPSI–IPent (IPent=diisopentylphenylimidazolium derivative) demonstrated high efficiency over a variety of challenging aryl or heteroaryl halides

  在杂芳基锡烷与芳基或杂芳基卤化物之间的Stille-Migita交叉偶联反应中，评估了Pd-PEPPSI（吡啶，增强型，预催化剂，制备，稳定化和引发反应）预催化剂的反应性。通常，与Pd-PEPPSI-IPr相比，Pd-PEPPSI-IPent（IPent =二异戊基苯基咪唑鎓衍生物）对各种具有挑战性的芳基或杂芳基卤化物和噻吩，呋喃，吡咯和噻唑基有机锡具有高效率（ IPr ＝二异丙基苯基咪唑鎓衍生物）。与基于三芳基膦的Pd催化剂相比，转化过程在较低的温度下（30–80°C）进行，从而扩大了这种有用的碳-碳键形成过程的范围。

  3a exhibited extremely high catalytic activity toward Negishi cross-coupling of alkylzinc reagents with a wide range of (hetero)aryl halides under mild reaction conditions within 30 min. Besides a great number of bromoarenes, various less expensive and inactive (hetero)aryl chlorides were coupled successfully with the alkyl- and arylzinc reagents, in which active functional groups (such as -NH2) were

  考虑到衍生自π-延伸的咪唑鎓盐的亚烷基的强大的σ-供体性质有利于提高所得钯N-杂环卡宾配合物的催化活性，因此制备了具有健壮的并咪唑-亚烷基钯配合物3a - c，具有不同的大取代基团通过在纯净的3-氯吡啶中与PdCl 2和K 2 CO 3加热，从相应的啶咪唑氯化物中得到满意的收率。即使在催化剂负载量低至0.25 mol％的情况下，配合物3a在温和的反应条件下，在30分钟内显示出对烷基锌试剂与各种（杂）芳基卤化物的Negishi交叉偶联极高的催化活性。除了大量的溴代芳烃外，还成功地将各种较便宜且不活泼的（杂）芳基氯化物与烷基-和芳基锌试剂偶联，其中具有活性官能团（例如-NH 2））即使在无保护的一锅双偶转换中也具有良好的耐受性。此外，在与仲烷基锌试剂偶联的情况下，有效抑制了导致异构化的线性产物的不希望的β-氢化物消除。通过杂芳基锌试剂和杂环氯代芳烃的偶联，该催化剂体系还显示出在杂二芳基结构方面

  Lithium and nickel complexes bearing quinoline-based ligands have been synthesized and characterized. Reaction of 8-azidoquinoline with Ph2PNHR (R = p-MeC6H4, But) affords N-(8-quinolyl)iminophosphoranes RNHP(Ph2)N(8-C9H6N) (1a, R = p-MeC6H4; 1b, R = But. C9H6N = quinolyl)). Reaction of 1a with (DME)NiCl2 generates a nickel complex [NiCl2N(8-C9H6N)P(Ph2)NH(p-MeC6H4)}] (2a). Treatment of 1b with (DME)NiCl2 and following with NaH produces [NiCl(1,2-C6H4)P(Ph)(NHBut)N(8-C9H6N)}] (4). Complex 4 was also obtained by reaction of (DME)NiCl2 with [Li(1,2-C6H4)P(Ph)(NHBut)N(8-C9H6N)}] (5) prepared through lithiation of 1b. Reaction of 2-PyCH2P(Ph2)N(8-C9H6N) (6, Py = pyridyl) and PhNC(Ph)CH2P(Ph2)N(8-C9H6N) (8), respectively, with (DME)NiCl2 yields two five-coordinate N,N,N-chelate nickel complexes, [NiCl22-PyCH2P(Ph2)N(8-C9H6N)}] (7) and [NiCl2PhNC(Ph)CH2P(Ph2)N(8-C9H6N)}] (9). Similar reaction between Ph2PCH2P(Ph2)N(8-C9H6N) (10) and (DME)NiCl2 results in five-coordinate N,N,P-chelate nickel complex [NiCl2Ph2PCH2P(Ph2)N(8-C9H6N)}] (11). Treatment of [(8-C9H6N)NP(Ph2)]2CH2 (12) [prepared from (Ph2P)2CH2 and 2 equiv. of 8-azidoquinoline] with LiBun and (DME)NiCl2 successively affords [NiCl(8-C9H6N)NP(Ph2)}2CH] (13). The new compounds were characterized by 1H, 13C and 31P NMR spectroscopy (for the diamagnetic compounds), IR spectroscopy (for the nickel complexes) and elemental analysis. Complexes 2a, 4, 7, 9, 11 and 13 were also characterized by single-crystal X-ray diffraction techniques. The nickel complexes were evaluated for the catalysis in the cross-coupling reactions of arylzinc reagents with aryl chlorides and aryltrimethylammonium salts. Complex 7 exhibits the highest activity among the complexes in catalyzing the reactions of arylzinc reagents with either aryl chlorides or aryltrimethylammonium bromides.
