PURPOSE:To obtain 2-alkyl, 6- or 7-formyltetralin by reacting 2-alkyltetralin with CO in the presence of CO and to obtain 6-alkyl, 7-formyltetralin by the similar reaction of 6-alkyltetralin. CONSTITUTION:2-Alkyl, 6- or 7-formyltetralin is produced by reacting a 2- alkyltetralin (especially preferably 2-methyltetralin, 2-ethyltetralin, 2- isopropyltetralin or 2-butyltetralin) with carbon monoxide in the presence of an acid catalyst (especially preferably HF-BF3, CF3SO3H, AlCl3-HCl, AlBr3-HBr or SbF5-HF). Similar reaction of 6-alkyltetralin (preferably alkyl is methyl, ethyl, isobutyl or butyl) gives a 6-alkyl, 7-formyltetralin. USE:Raw material for 2,6-naphthalene. |
