Liu, Can;Shen, Ni;Shang, Rui research published 《 Photocatalytic defluoroalkylation and hydrodefluorination of trifluoromethyls using o-phosphinophenolate》, the research content is summarized as follows. Under visible light irradiation, o-phosphinophenolate functions as an easily accessible photoredox catalyst to activate trifluoromethyl groups in trifluoroacetamides, trifluoroacetates and trifluoromethyl (hetero)arenes to deliver corresponding difluoromethyl radicals. It works in relay with a thiol hydrogen atom transfer (HAT) catalyst to enable selective defluoroalkylation and hydrodefluorination. The reaction allowed for the facile synthesis of a broad scope of difluoromethylene-incorporated carbonyl and (hetero)aromatic compounds, which are valuable fluorinated intermediates of interest in the pharmaceutical industry. The ortho-diphenylphosphino substituent, which is believed to facilitate photoinduced electron transfer, plays an essential role in the redox reactivity of phenolate. In addition to trifluoromethyl groups, pentafluoroethyl groups could also be selectively defluoroalkylated.

Here, 1,2-bis(dicyclohexylphosphino)ethane Fe-catalyzed coupling of α-boryl radicals (generated from selective radical addition to vinyl boronates) with Grignard reagents was demonstrated. Then, the scope of these radical cascades was extented by developing a general and broadly applicable Fe-catalyzed multicomponent annulation-cross-coupling protocol that engages a wide range of π-systems and permits the practical synthesis of cyclic fluorous compounds Mechanistic studies are consistent with a bisarylated Fe(II) species being responsible for alkyl radical generation to initiate catalysis, while carbon-carbon bond formation proceeds between a monoarylated Fe(II) center and a transient alkyl radical.

The stannum-ene reactions of both benzyne and cyclohexyne were realized, which is particularly suitable for cyclohexyne with a broad substrate scope and excellent chemoselectivity. Our DFT calculations via distortion/interaction anal. revealed that both stannum- and hydrogen-ene reactions with cyclohexyne have later transition states due to their higher distortion energies in the transition states than those in benzyne reactions, which lead to enhanced Pauli repulsion as the decisive factor in the interaction energy accompanied with enlarged energy gap between two types of ene reactions. Therefore, excellent chemoselectivity was disclosed in the cyclohexyne-ene reaction.

Li, Mengwen;Ao, Shen;Liang, Yueqi;Hao, Zhen;Hao, Xiaohui;Liu, Xueliang;Sun, Xinchao;Yang, Yunxu research published 《 The selective and sensitive detection of formaldehyde by ZIF-90-LWvia aza-Cope rearrangement》, the research content is summarized as follows. Formaldehyde (FA), as one of the simplest reactive carbonyl species (RCS), is widely known as an environmental toxin and carcinogen. In this work, a new ZIF-90 type material (ZIF-90-LW) was synthesized and investigated, which combines the two strategies of “2-aza-Cope rearrangement” and “MOF structure”, by the combination of a pre-functionalized 2-allylaminoimidazole ligand and Zn²⁺ salt under solvothermal conditions. From this, the hurdle of selectivity over other carbonyl compounds (RCS) could be overcome despite their similar electrophilic reactivities to FA, and a prominent fluorescence turn-on type signal was realized through the 2-aza-Cope rearrangement mechanism. A good linear relationship (R2 = 0.9979) was obtained by fitting the fluorescence intensity towards FA from 0 to 25 mM, and the detection limit of ZIF-90-LW for FA was 2.3 μM. In addition, it also showed potentially useful sensing ability for the detection of FA in the gas phase, and might therefore be used to rapidly detect FA with a response time of 28 s in the liquid phase. All of the above features clearly demonstrate that ZIF-90-LW has great potential for sensitive and selective recognition of FA in the environment.
