described. The transition-metal-free approach, readily available reagents, and mild conditions provide a practical way for the synthesis of difluoromethyl thioethers. By changing the “H” source to the most commonly used “D” sources CD3OD and D2O, this strategy enables efficient synthesis of SCF2D-substituted molecules in good yields with high levels of D incorporation.
描述了烷基亲电试剂与硫脲和溴代二氟甲基膦酸二乙酯的一锅二氟甲基硫醇化。不含过渡金属的方法,容易获得的试剂和温和的条件为合成二氟甲基硫醚提供了一种实用的方法。通过将“ H”源更改为最常用的“ D”源CD 3 OD和D 2 O,此策略能够以高收率和高D掺入量高效合成SCF 2 D取代分子。
