  A series of benzo[c]chromen-6-ones are prepared by a Suzuki coupling and lactonization sequence starting with 2-methoxyphenylboronic acids and methyl 2-bromobenzoate derivatives. The use of ionic liquids in this synthesis has been explored. It was found that the Suzuki coupling proceeds much faster when a catalytic amount of the ionic liquid [BMIM][PF6] is used. By using the Lewis acidic ionic liquids
