| titleOfInvention | Enrichment for the preparation of 3-isochromanone |
| abstract | The invention relates to a method for producing possibly substituted 3-isochromanone of the formula (I), according to which 2-halogen methyl phenyl acetonitriles of the formula (II) are reacted with a halogen acid. In said formulas R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP> and R<SP>4</SP> are identical or different and represent H, halogen, OH or OR<SP>5</SP>, R<SP>5</SP> representing a C<SB>1</SB>-C<SB>4</SB>-alkyl, or R<SP>1</SP> and R<SP>2</SP> or R<SP>2</SP> and R<SP>3</SP> or R<SP>3</SP> and R<SP>4</SP> together form a C<SB>3</SB>- or C<SB>4</SB>-alkyl rest or a C<SB>3</SB>- or C<SB>4</SB>-alkylene rest and X is chlorine or bromine. |
