Versuchsvorschrift

A Grignard reaction mixture was prepared by contacting 100 mL of 2M phenylmagnesium chloride in tetrahydrofuran with 0.1 mole m-diacetyl benzene. 100 mL of n-octanol were added to the Grignard reaction mixture. The tetrahydrofuran was removed by distillation during which the pot temperature rose to 175° C. in 2 hours. Gas chromatograph analysis showed that the alcohol had been dehydrated to m-bis-(1-phenylethenyl) benzene. Product yield was about 95%
