1.引言关于氯铬酸吡啶(PCC)的反应活性,虽然于1975年以前的少数资料中可以得到,但直到Corey和他的同事们研究之前还很少有人研究过。 2.醇的氧化 2.1 早期的研究为了使醇氧化成羰基化合物的操作简化,寻找温和、通用的选择性试剂,是长期以来许多实验室研究的课题。人们研究了许多含铬(Ⅵ)离子的试剂,但其中的大多数不适用于现代有机合成,特别是对于那些复杂的或高度敏感的物质的氧化或制备。
1. INTRODUCTION Reactivity with pyridinium chlorochromate (PCC), although available from a few sources up to 1975, has not been studied by much until Corey and his colleagues studied it. 2. Oxidation of alcohols 2.1. Early studies In order to simplify the oxidation of alcohols to carbonyl compounds, the search for mild, versatile and selective reagents has long been the subject of many laboratory studies. Many chromium (VI) ion containing reagents have been studied, but most of them are unsuitable for modern organic synthesis, especially for the oxidation or preparation of complex or highly sensitive materials.
