Reaktionsschritte

A convenient synthesis into 3,3-dimethyl indan-1-one is via the acid catalysed cyclisation of phenylisobutyric acid. The phenylisobutyric acid may be prepared by reaction of neophylchloride with magnesium followed by carbon dioxide under known conditions. Typically, one obtains phenylisobutyric acid in admixture with an unwanted coupling product 2,5-dimethyl-2,5-diphenyl hexane.
