Participants

Reaction Steps

A Grignard reagent, prepared by reacting 11.8 g (0.49 g atom) of magnesium in 50 ml of ether and 67.13 g (0.49 mol) of isobutyl bromide in 250 ml of ether, is reacted with 40.0 g (0.41 mol) of 2-methyl-2-pentenal in 100 ml of ether in a manner analogous to Example 5. Fractional distillation of the crude product (94 g) over a 20 cm Widmer column give 44.4 g (69.4%) of olfactorily good 4,7-dimethyl-3-octen-5-ol of boiling point 47°-48° C./0.04 mm Hg.
