Tin-containing Indane and Tetralin Derivatives

Abstract

The preparation of tin-containing indane and tetralin derivatives via two different reaction pathways is reported. The first route is the reaction of dichlorostannanes or bis(fluoroalkylsulfonyl)stannanes withα,α'-di(chloromagnesium)xylene. The second reaction is the direct coupling of chlorostannanes and α,α'-dichloroxylene which always yields a mixture of tin-containing indanes and tetralins. The separation of these compounds can easily be achieved by fractional crystallization. By these simple and effective routes the first 2,3-distannatetralins were synthesized
