Alcohols are widely available, abundant, and diverse in both commercial and natural resources. They possess low toxicity, making their use as reactants for carbonylation extremely promising. Herein, we present a robust ligand-controlled regioselective aminocarbonylation of -alcohols. Utilizing a commercially available palladium salt and ligand as the catalytic system, various amides containing an α-quaternary carbon or β-substituted amides can be selectively accessible. Notably, water is the only by-product of this reaction, which is consistent with the concept of green chemistry. This protocol offers a broad substrate scope, high regioselectivity, and excellent performance in scale-up reactions.
醇类在商业和自然资源中广泛可得、储量丰富且种类多样。它们毒性低,用作羰基化反应的反应物极具前景。在此,我们展示了一种稳健的配体控制的α-醇区域选择性氨羰基化反应。使用市售钯盐和配体作为催化体系,可以选择性地获得各种含有α-季碳的酰胺或β-取代酰胺。值得注意的是,水是该反应的唯一副产物,这与绿色化学的理念相符。该方法具有广泛的底物范围、高区域选择性以及在放大反应中的优异性能。
