STRUCTURE OF THE SIDE PRODUCTS IN THE SYNTHESIS OF 4-ACETYL-1,1-DIMETHYL-6-TERT-BUTYLINDANE

Smirnova, O. B.,Cherkaev, G. V.,Shekhtman, N. M.

, p. 2123 - 2127 (2007/10/02)

The minor products from the acetylation of 1,1-dimethyl-6-tert-butylindane with acetyl chloride were isolated and identified by PMR spectroscopy.The configuration of the substituents in isomeric compounds with an identical type of substitution in the aromatic ring was established by means of the long-range spin-spin coupling constants of the aromatic protons with the protons of the five-membered ring.
