In the presence of cadmium (II) chloride-metallic samarium, alpha-bromoacetophenone reacts with aldehydes in THF -H2O under mild conditions to give beta-hydroxy ketones in good yields.
1-（β-Hydroxyalkyl）-l,3,4-oxadiazole derivatives were synthesized via reductive addition reactions of 2-chloromethyl-l,3,4-oxadiazole with carbonyl compounds under mild conditions promoted by SmI2.
Treatment with Sin-CdCI2-HMPA system, dibenzyl and diphenyl diselenides react withacyl handes and acid anhydrides in one-pot to give corresponding selenoesters in good yields undermild and neutral conditions.
