Alkylation of Phenol And Hydroquinone by Prenol in the Presence of Organoaluminum Catalysts
Chukicheva, I. Yu.,Fedorova,Koroleva,Kuchin
, p. 1 - 6 (2018/02/19)
Prenylphenols and 2,2-dimethylbenzopyrans were synthesized via alkylation of phenol and hydroquinone with prenol in the presence of organoaluminum catalysts, i.e., aluminum phenoxide and isopropoxide. Reaction products were isolated and characterized. Sev
Synthesis of 1,1-dimethyl-4-indanol derivatives

The synthesis of 1,1-dimethyl-4-indanols (3a,b) has been achieved by intramolecular Friedel-Crafts cyclization of 2-(3-methyl-2-butenyl)phenols (5a,b) or 1-methoxy-2-(3-methyl-2-butenyl)benzenes (6a,b) followed by demethylation, respectively. It was found that the solvent was critical for the formation of different products in the intramolecular Friedel-Crafts reactions of 6. The unexpected product 4-methoxy-1,1,6,6-tetramethyl-as-hydrindacene (11) was obtained from the Friedel-Crafts reactions of 6a and its structure was confirmed by X-ray diffraction analysis. The key intermediates 5a,b were prepared by ortho-alkenylation of phenols with 1-bromo-3-methyl-2-butene, and the reaction temperature exerted an obvious impact on the yield of 2-(3-methyl-2-butenyl)phenol (5a).

REGIOSPECIFIC ALKENYLATION OF PHENOLS BY 1,1-DIMETHYLALLENE PROMOTED BY PLATINUM CATALYSTS
Renzi, Augusto De,Panunzi, Achille,Saporito, Antonio,Vitagliano, Aldo
, p. 993 - 996 (2007/10/02)
1,1-Dimethylallene reacts with phenolic substrates in the presence of catalytic amounts of platinum(II) complexes.A regiospecific C-alkenylation takes place, affording o-isopentenylphenols and 2,2-dimethylchromans.Possible reaction mechanisms are also discussed.
