In 2018,Lan, Yun; Yang, Feiyan; Wang, Chuan published 《Synthesis of gem-Difluoroalkenes via Nickel-Catalyzed Allylic Defluorinative Reductive Cross-Coupling》.ACS Catalysis published the findings.Application In Synthesis of tert-Butyl 4-iodopiperidine-1-carboxylate The information in the text is summarized as follows:
In this protocol, we report an allylic defluorinative reductive cross-coupling reaction for C-C bond formation. Under the Ni-catalysis the challenging C(sp3)-F bond cleavage of trifluoromethyl-substituted alkenes was achieved with easily accessible primary, secondary and tertiary alkyl halides as the coupling partners and Zn-powder as reducing agent. This process provides an efficient and convenient entry to gem-difluoroalkenes bearing various sensitive functional groups under mild reaction conditions. Moreover, this method proves to be suitable for late-stage functionalization of multifunctional complex mols. In the experiment, the researchers used tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3Application In Synthesis of tert-Butyl 4-iodopiperidine-1-carboxylate)
tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Application In Synthesis of tert-Butyl 4-iodopiperidine-1-carboxylate
