Versuchsvorschrift

Hexadecenyl bromide (360 g; 1.2 mol) and 1800 mL (2660 g; 34 mol) of DMSO were mixed and heated to 60° C. for 30 minutes. Then, NaHCO3 and a co-solvent were added, pressure reduced and temperature raised for the period of time specified in Table I. Reaction mixture was then cooled and concentrated on a rotary evaporator. GLC analysis was then carried out to determine aldehyde/alcohol ratios in the reaction product. Results from reactions employing several different co-solvents are summarized in Table I as runs 5-9.
