La formylation catalysee par le palladium d'une variete de substrats organiques (iodoarenes, halogenures benzyliques, iodures vinyliques, triflates de vinyles et halogenures allyliques) avec le tributylstannane et le monoxyde de carbone donne les aldehydes avec de bons rendements dans des conditions douces et tolere un certain nombre de groupes fonctionnels

Here we report that enol nonaflates exhibit higher reactivity than the corresponding enol triflates in palladium-catalyzed cross-coupling reactions with various (vinyl)tributylstannanes and acetylenes. We also highlight the reaction of a vinyl nonaflate, containing two 1 3 C-labeled carbon atoms with an alkenyl stannane, which afforded the trisubstituted E-olefin stereoselectively in high yield. The
在这里,我们报告烯醇九氟甲磺酸酯在钯催化的与各种(乙烯基)三丁基锡烷和乙炔的交叉偶联反应中表现出比相应的烯醇三氟甲磺酸酯更高的反应性。我们还强调了含有两个 1 3 C 标记的碳原子的乙烯基九烷基锡与烯基锡烷的反应,它以高产率立体选择性地提供了三取代的 E-烯烃。然后将 E-烯烃转化为相应的全 E-视黄醛。
Synthesis of New Highly Functionalized 1H-Indole-2-carbonitriles via Cross-Coupling Reactions
for the preparation of polysubstituted indole-2-carbonitriles through a cross-coupling reaction of compounds 1-(but-2-ynyl)-1H-indole-2-carbonitriles and 1-benzyl-3-iodo-1H-indole-2-carbonitriles is described. The reactivity of indole derivatives with iodine at position 3 was studied using cross-coupling reactions. The Sonogashira, Suzuki–Miyaura, Stille and Heck cross-couplings afforded a variety of

A new synthetic method of N-methoxy-N-methylamides is developed. The palladium-catalyzedcouplingreaction of N-methoxy-N-methylcarbamoyl chloride furnished N-methoxy-N-methylamide in moderate to good yield, wherein a carbonyl equivalent was appended to sp and sp2 carbon atoms as a versatile synthetic basis for further manipulation.
