Ethylene → 7-Bromo-2-tetralone

Participants

Reaction Steps

Scheme 3 illustrates a route to 7-substituted tetralin derivatives 10 and 11. 3-Bromophenylacetic acid is converted to the corresponding acid chloride and this is subjected to Friedel—Crafts reaction with ethene, affording the 7-bromo-2-tetralone 9. This intermediate may be elaborated using the procedures described in Scheme 1 to provide the acid (10) and aniline (11).
