promoting the thiocarbonylation of acyl halides and thiols is disclosed. HFIP was recovered with ease and reused for further reactions without any loss of reactivity. Both aryl and alkyl thiols bearing electron-donating and electron-withdrawing groups as well as aryl- and alkyl acyl halides worked well in this reaction. Inexpensive precursors, short reaction time, obviating workup, high atom economy, and
已经开发出一种新颖,有效,无金属,无碱和无酸的简单方法来构建有用的硫酯。公开了HFIP促进酰基卤和硫醇的硫羰基化的巨大催化潜力。可以轻松回收HFIP,并重新用于进一步反应,而不会损失任何反应性。带有给电子基团和吸电子基团的芳基和烷基硫醇以及芳基和烷基酰基卤在该反应中均表现良好。廉价的前体,短的反应时间,避免后处理,高原子经济性和克级制备是发达的硫醇S-羰基化生态友好路线的重要特征。
