Kinetics and Mechanism of Unimolecular Heterolysis of Framework Compounds: XVII. Solvation Effects in Dehydrobromination of tert-Butyl Bromide, 1-Bromo-1-Methylcyclohexane, and 2-Bromo-2-methyladamantane in Dipolar Aprotic Solvents
Reported herein is a novel visible‐light photoredox system with Pd(PPh3)4 as the sole catalyst for the realization of the first direct cross‐coupling of C(sp3)−H bonds in N‐aryl tetrahydroisoquinolines with unactivated alkyl bromides. Moreover, intra‐ and intermolecular alkylations of heteroarenes were also developed under mild reaction conditions. A variety of tertiary, secondary, and primary alkyl

A novel reductive cross-coupling of arylvinylhalides and unactivated tertiary alkyl bromides has been realized via photoredox/nickel dual catalysis to produce vinyl arene derivatives bearing all-carbon quaternary centers with excellent E-selectivity. A stoichiometric metal reductant could be avoided by employing commercially available N,N,N′,N′-tetramethylethylenediamine (TMEDA) as the terminal reductant

We describe here the facile construction of sterically hindered tertiary alkyl ethers and thioethers via the Zn(OTf)2-catalyzed coupling of alcohols/phenols with unactivated tertiary alkyl bromides and the Cu(OTf)2-catalyzed thiolation of unactivated tertiary alkyloxalates with thiols. The present protocol represents one of the most effective unactivated tertiary C(sp3)–heteroatom bond-forming conditions
