Abstract

gem-Dialkylation or alkylative reduction of α-unbranched aliphatic aldehydes 1 is advantageously achieved by reaction of the corresponding gem-bistriflates 2 with di-n- alkylcyanocuprates or di-sec-and di-tert-alkylcyanocuprates respectively. The reaction of α- branched gem-bistriflates 2 with dialkylcyanocuprates in the presence of boron trifluoride affords the olefins 6 in good yield.
