Process for the preparation of substituted indanones |
| abstract |
Abstract of the Disclosure Process for the preparation of substituted indanones 1-Indanones of the formula IV or IVa (IV) (IVo) in which R1 to R7 are preferably hydrogen or alkyl, or adjacent radicals R1 to R4 form a ring, are obtained in a one-step reaction by reacting a compound I ( I ) with a compound of the formula II ( II ) or with a compound of the formula (III) ( I I I ) in anhydrous hydrogen fluoride and with boron trifluoride. |
