Participants

Reaction Steps

163 g (1 mole) of 1,5-dichloro-3,3-dimethyl-pent-1-en-4-ine and 232 g (2 moles) of sodium phenolate in 1 liter of absolute N,N-dimethylformamide are heated to 140° C. in the course of 3 hours and stirring is then continued for 4 hours. The mixture is worked up as described for method A, giving 204 g of crude product, which after distillation (boiling point 0.15/87°-94° C.) gives 141 g (that is to say 64% of theory) of 1-chloro-3,3-dimethyl-2-phenoxy-pent-1-en-4-ine.
