Abstract:
Electrochemistry is used for propargylation of carbonyls in aqueous ZnCl2 medium. For electrochemical process we designed a unit galvanic cell. ZnCl2 is used as stoichiometric reagent and causes electrochemical deposition of zinc in cathode. Wire shaped nano zinc architecture has been formed in cathode during electrochemical process which is the active reagent. Homopropergylic alcohols are synthesized in good yields. After the organic reaction is over aqueous solution containing zinc salts can be reused up to 5th cycle without significant loss of reactivity.
