multicomponent coupling reaction of alkylhalides, isocyanides, and H2O to access alkyl amides. Bench-stable NiCl2(dppp) is competent to initiate this transformation under mild reaction conditions, thus allowing easy operation and adding practical value. Substrate scope studies revealed a broad functional group tolerance and generality of primary and secondary alkylhalides in this protocol. A plausible

A user‐friendly, nickel‐catalyzed reductive amidation of unactivated primary, secondary, and tertiary alkylbromides with isocyanates is described. This catalytic strategy offers an efficient synthesis of a wide range of aliphatic amides under mild conditions and with an excellent chemoselectivity profile while avoiding the use of stoichiometric and sensitive organometallic reagents.

Provided are compounds and methods of making compounds containing two or three groups derived from a peptide, such as enfuvirtide or exenatide, covalently bound to a linker. The compounds may contain polyethylene glycol groups to enhance solubility and pharmacokinetic properties. The compounds are useful for the treatment of diseases or conditions subject to treatment with the parent peptide, such as HIV and AIDS in the case of enfuvirtide, or diabetes in the case of exenatide.
Nickel-Catalyzed Formal Aminocarbonylation of Unactivated Alkyl Iodides with Isocyanides
iodides with isocyanides to afford alkyl amide, which proceeds via the selective monomigratory insertion of isocyanides with alkyl iodides, subsequent β-hydride elimination, and hydrolysis process. The reaction features wide functional group tolerance under mild conditions. Additionally, the selective, one-pot hydrolysis of reaction mixture under acid conditions allows for expedient synthesis of the corresponding
