mild and highly selective protocol for the monodeuteration of a variety of arenes and heteroarenes is presented. Catalytic amounts of Ag(I) salts in DMSO/D2O are shown to facilitate the deutero-decarboxylation of ortho-substituted benzoic and heteroaromatic α-carboxylic acids in high yields with excellent levels of deuterium incorporation.
提出了一种实用,温和且高度选择性的方案,用于多种芳烃和杂芳烃的单氘化。催化量的Ag(I)盐在二甲基亚砜已显示出/ D 2 O以高收率和良好的氘掺入水平促进了邻位取代的苯甲酸和杂芳族α-羧酸的氘代脱羧。
