This invention relates to a novel group 2, 3 or 4 transition metal metallocene catalyst compound that is asymmetric having two non-identical indenyl ligands with substitution at R2 having a branched or unbranched C1-C20 alkyl group substituted with a cyclic group or a cyclic group, R8 is an alkyl group and R4 and R10 are substituted phenyl groups.

Chemecal quation presented Excellent stereoselectivity is obtained in the synthesis of biologically interesting 1,2,3-trisubstituted indanes B by the reaction of readily prepared 3-substituted indenes A with commercially available arylboronic acids by using various TEMPO derivatives as external oxidants and Pd(OAc)2 as a catalyst. The anti,anti isomers are formed and reactions occur stereospecifically under mild conditions.
