Herein, we report a method that combines hydrogen atom transfer and photoredox catalysis to achieve the dehydrogenative difluoroallylation of amides, ethers, and alkyl aldehydes. This operationally convenient method transforms a broad scope of substrates into the corresponding gem-difluoroalkenes via the construction of C(sp3)–C(sp3) or C(sp3)–C(sp2) bonds. Excellent functional group compatibility
Three component hydroxyletherification and hydroxylazidation of (trifluoromethyl)alkenes: access to α-trifluoromethyl β-heteroatom substituted tertiary alcohols
The three component hydroxyletherification and hydroxylazidation reactions of (trifluoromethyl)alkenes are reported, providing various useful α-trifluoromethyl β-heteroatom substituted tertiary alcohols in high yields.

Herein, we describe an efficient, practical photocatalytic deoxygenation/defluorination protocol for the synthesis of γ,γ-difluoroallylic ketones from commercially available aromatic carboxylic acids, triphenylphosphine, and α-trifluoromethyl alkenes. The protocol has good functional group tolerance and a broad substrate scope. Using this method, we accomplished the late-stage functionalization of

gem-difluoroalkenes and organoboroncompounds. However, the strategies for the construction of gem-difluorohomoallyl boronates has scarcely been described. Herein, we develop an efficient protocol for the construction of gem-difluorohomoallylic boronates through a Ni-catalyzed radical-promoted defluoroalkylborylation of α-trifluoromethyl alkenes with α-haloboronates under mild conditions. This reaction features a
gem -Difluoroalkenyl boronates 是用于构建各种gem -difluoroalkenes和有机硼化合物的有吸引力的合成子。然而,几乎没有描述构建偕二氟高烯丙基硼酸酯的策略。在此,我们开发了一种有效的方案,用于在温和条件下通过 Ni 催化的自由基促进的 α-三氟甲基烯烃与 α-卤代硼酸酯的脱氟烷基硼酸化来构建偕二氟高烯丙基硼酸酯。该反应具有广泛的底物范围、良好的官能团耐受性和多种转化。
