Practical Preparation of Pentadecanol and 1 Bromopentadecane from 1 Hexadecene

WANG Zhe Qing (Shanghai Institute of Pharmaceutical Industry, Shanghai 200040)  
Hexadecene was treated with ozone at low temperature to form its ozonide, which was reduced with sodium borohydride to 1 pentadecanol in 94.5% overall yield.1 Bromopentadecane was in turn prepared from pentadecanol via bromination under PTC condition in 92.5%.The whole process is believed to be applicable to the preparation of odd number aliphatic straight chain alcohols and halides as well.It has the advantages of low cost,less pollution and easy manipulation over Hunsdiecker Borodine reaction for synthesis of certain alkyl halides.
