The title compound 4 is formed in fair yield in addition to the oligomers of isobutene during synthesis of 3-tert-butyl-2,4-pentanedione (2) from 2,4-pentanedione (1) with tert-butylalcohol and perchloric acid in nitromethane.Acid-catalyzed condensation of 1 with isooctene 5 is discovered to be responsible for the formation of 4.This reaction yields other meta-neopentyl-substituted benzene derivatives (19,20,21) with several β-diketones.
