Convenient preparation of benzylseleno- and phenylselenoalkanoic acids: Reagents for synthesis of organoselenium compounds

Bhalla, Aman,Sharma, Sitansh,Bhasin, Kuldip K.,Bari, Shamsher S.

, p. 783 - 793 (2007/10/03)

An efficient and operationally simple route to benzylseleno- and phenylselenoalkanoic acids from ethyl benzyl/phenylselenoalkanoates is described. This involves preparation of ethyl benzyl/phenylselenoalkanoates as substrates by reaction of dibenzyl/diphenyl diselenide and sodium borohydride with ethyl chloroalkanoates in ethanol followed by basic hydrolysis and subsequent acidification.
