Process for the preparation of 2-alkylsulfonyl-4-alkyl-phenols |
| abstract |
Compound of formula I. with R¹ and R² equal to alkyl are obtained if 4-alkylanisoles of the formula II sulfochlorinated at temperatures below 0 ° C. and the resulting compounds in a one-pot process to give compounds IV reduced which are alkylated. Ether cleavage with HBr then leads to I. |
