Addition of tetrachloromethane to oct-1-ene initiated by amino alcohols

The kinetics and mechanism of an addition of CCl₄ to oct-1-ene initiated by amines, aromatic alcohols, and amino alcohols (structural analogs of ephedrin) were studied. The radical mechanism of the reaction was established by ESR using the technique of spin traps. Aromatic amino alcohols as initiators are more active than amines and aromatic alcohols of similar structure. They are more selective compared to the amines and aromatic alcohols and react with CCl₄ already at room temperature to form predominantly benzaldehyde. The scheme of initiation by aromatic amino alcohols of the addition of CCl₄ to olefins was proposed on the basis of the experimental data. Published in Russian in Izvestiya Akademii Nauk.
