reactions of a variety of aldehydes with aqueous ammonia, molecular iodine, and O,O-diethyl dithiophosphoric acid readily afford the corresponding primary thioamides. This is an inexpensive, practical, and metal-free way of accessing various thioamides from aldehydes in aqueous media. The pure products are obtained simply by filtration followed by successive washing with aqueous sodium thiosulfate
摘要 多种醛与氨水、分子碘和 O,O-二乙基二硫代磷酸的一锅串联反应容易得到相应的伯硫代酰胺。这是一种廉价、实用且无金属的方法,可以在水性介质中从醛中获取各种硫代酰胺。简单地通过过滤然后用硫代硫酸钠水溶液和水连续洗涤来获得纯产物。[本文提供补充材料。访问出版商的 Synthetic Communications® 在线版,获取以下免费补充资源:完整的实验和光谱细节。] 图形摘要
