Participants

Procedure

626 g (3 moles) of 1,1-dichloro-3-ethyl-3-methyl-1-heptene and 676 g (6 moles) of sodium phenolate are heated under relfux in 3 l of dimethylformamide for 16 hours. The mixture is diluted with methylene chloride and extracted by shaking several times with 2N aqueous sodium hydroxide solution. After drying and evaporating on a rotary evaporator, 666 g of crude product remain. Distillation at boiling point0.1 100°-110° C. gives 523 g (65% of theory) of 1-chloro-3-ethyl-3-methyl-2-phenoxy-hept-1-ene.
