Heavy stuff: A triethylamine‐mediated H–D exchange reaction for the conversion of unlabeled alkynes (1) into [D1]alkynes ([D1]‐1) in a mixture of D2O/THF has been developed. Furthermore, the efficient preparation of site‐ and regioselectively deuterated alkenes ([Dn]‐2) from 1 or [D1]‐1 with palladium on boron nitride (Pd/BN) as the catalyst and gaseous H2 or D2 is discussed. The resulting deuterated
重物:已开发出一种三乙胺介导的H–D交换反应,用于在D 2 O / THF的混合物中将未标记的炔烃(1)转化为[D 1 ]炔烃([D 1 ] -1)。此外,位点的有效制备和区域选择性地氘化的烯烃([d Ñ ] - 2)从1或[d 1 ] - 1,以钯氮化硼(钯/ BN)作为催化剂和气态ħ 2或d 2讨论。所得氘代产品是用于合成标记化合物的有吸引力且功能强大的工具,这些标记化合物可在一系列科学领域中使用(请参阅方案)。
