Participants

Reaction Steps

5,5-Dimethyl-4-oxocaproaldehyde cl was prepared analogously to al by reaction of pivaloyl chloride and allyl chloride (see I.1.). 41 g (195 mmol) of c1 were reacted with cyclopentadiene and potassium tert-butylate and the mixture was worked up, analogously to instructions I.1. The reaction time was 19 hours at room temperature. Column chromatography gave 3.2 g (10%) of indene c2 as a yellow oil (2 double bond isomers).
