A simple and efficient visible-light photoredox one-pot method for difluoromethylation of phenols and thiophenols has been developed. The protocol uses commercially available, inexpensive, and easy handling difluorobromoacetic acid as the difluoromethylating agent, and the diverse O- and S-difluoromethylated products were prepared in good yields with tolerance of many functional groups.
已开发出一种简单有效的酚和硫酚二氟甲基化的可见光氧化还原一锅法。该方案使用可商购的,廉价的和易于处理的二氟溴乙酸作为二氟甲基化剂,并且以高收率制备了多种O-和S-二氟甲基化产物,并具有许多官能团的耐受性。
