✦ Synopsis

Styrene was polymerized using a series of methylaluminoxane-activated bis(pheno1ato)titanium complexes of the type

Nine new fluorinated half-sandwich titanocene complexes (1b-9b) based on substituted alkylindenes were synthesized, by reacting Me 3 SnF with the corresponding chloride species, and employed as catalyst precursors for the syndiospecific polymerization of styrene. When activated with methylaluminoxan
