• We have designed novel catalysts for radical bromination of alkanes with CBr4.
• Addition of n-PrOH to the catalytic reaction leads to positive yield effect.
• The temperature dependence of the monobromodecanes yield has an extremal character.
• The monobromodecanes yield extremely depends on the alcohol concentration.
New catalytic systems with supported bromine- and chlorine-containing copper complexes for selective bromination of alkanes with tetrabromomethane have been proposed. Introduction of donor additives (e.g., low-molecular-weight alcohols) into the reaction increases the activity and stability of these catalysts. The kinetic features of the processes have been investigated. It has been shown that the dependences of the yield of bromodecanes on temperature and concentration of donor additives are both nonmonotonic in character.
