Abstract:

The regioselective Friedel-Crafts acylation of 1,2-bis(2-methylbenzo{[}b]thien-3-yl)hexafluorocyclopentene was developed. Depending on the reaction conditions, mono- or bis(bromoacetyl) derivatives are formed as single products in good yields. Further heterocyclizations involving alpha-bromoketone moieties gave a series of new photochromic compounds. (C) 2012 Elsevier Ltd. All rights reserved.
