A metal-free catalytic oxidation of α-diazoesters a green environmental-friendly route was developed. The α-diazoesters were converted to α-ketoesters using DMF and molecular oxygen as oxygen sources and B(CF) as the catalyst, without any additives. This protocol has a broad adaptability of substrates and good compatibility with a range of functional groups, and it offers new insight into reactions catalyzed by B(CF).
开发了一种无金属催化氧化α-重氮酯的绿色环保路线。以DMF和分子氧作为氧源，B(CF)作为催化剂，在无任何添加剂的情况下，α-重氮酯被转化为α-酮酯。该方案对底物具有广泛的适应性，与一系列官能团具有良好的兼容性，并为B(CF)催化的反应提供了新的见解。
