| Abstract
| - A convenient synthetic method of unsymmetricalselenides has been developed. When diphenyl diselenide wasallowed to react with two equimolar amounts of primaryalkyl iodides and bromides in the presence of an equimolaramount of lanthanum metal, alkyl phenyl selenides wereformed in moderate to good yields. For the reaction ofprimary alkyl chlorides and secondary alkyl iodides, theyields of the selenides were low; however, the yields weredramatically improved by the addition of TMEDA or HMPA.A reaction pathway involving the generation of a lanthanumphenylselenolate intermediate was suggested.
