C-F activation for C(sp2)-C(sp3) cross-coupling by a secondary phosphine oxide (SPO)-nickel complex

A secondary phosphine oxide (SPO)-nickel catalyst allowed the activation of otherwise inert C-F bonds of unactivated arenes in terms of challenging couplings with primary and secondary alkyl Grignard reagents. The C-F activation is characterized by mild reaction conditions and high levels of branched selectivity. Electron-rich and electron-deficient arenes were suitable electrophiles for this transformation. In addition, this strategy also proved suitable to heterocycles and for the activation of C-O bonds under slightly modified conditions.

Highly regio- and stereoselective palladium-catalyzed allene bifunctionalization cascade via π-allyl intermediate

We report a palladium-catalyzed allene bifunctionalization reaction that forms C–C and either C–O or C–N bonds in one pot with excellent regio- and stereoselectivity. Carboxylic acids, amides, and hydroxide are all suitable nucleophiles. Organoboronic acid acts as hydroxide transfer reagent. An intermediate π-allyl palladium complex was isolated, which yields improved catalytic performance as well as evidence of the origin of stereoselectivity. A derivatization study emphasizes the utility of the functionalized allylic products.

Thermal transformations of 4-tert-butylbiphenyl

The thermal stability of 4-tert-butylbiphenyl was studied in the range of 703-763 K. The competition of the cracking and isomerization reactions of alkyl substituents on the aromatic ring of the reactant and its products has been revealed. The kinetic characteristics of the complex of transformations occurring in the system have been determined. Recommendations are provided regarding the conditions for the determination of the critical parameters of 4-tert-butylbiphenyl and for the processing and use of compounds with a tert-butyl moiety in the molecule.
