Versuchsvorschrift
15.8 g pyridinium dichromate in 300 ml dichloromethane were initially introduced under blanketing gas and 5.93 g (Z)-8-tetradecen-1-ol (5) in 50 ml dichloromethane was added, with stirring. The reaction mixture was stirred for 15 h at room temperature and filtered through silica gel. Distillation under a high vacuum gave (Z)-8-tetradecenal (6).
