Abstract

o-(Silylmethyl) benzylic carbonates reacted with various conjugated olefins in the presence of the palladium catalyst, which was generated in situ from Pd (η3-C3H5) Cp and 1, 2-bis (diphenylphosphino) ethane (DPPE). The reaction provided 2-and/or 3-substituted tetralins in good yield. The catalytic reaction described here is equivalent to the [4+ 2] cycloaddition of o-xylylenes with dienophiles.
