General description

4-Methylstyrene is a molecule with an extended Π conjugation. The threefold symmetric torsional potential of 4-methylstyrene has been investigated. Polymerization of 4-methylstyrene by employing a half-metallocene type catalytic system composed of (trimethyl)pentamethylcyclopentadienyltitanium (Cp*TiMe3), trioctylaluminum (AlOct3), and tris(pentafluorophenyl)borane [B(C6F5)3] has been reported. Palladium-catalyzed Heck coupling of chlorobenzene with 4-methylstyrene has been investigated.

Application

4-Methylstyrene was employed as Π ligand in the preparation of cationic, two-coordinate triphenylphosphine-gold(I)-Π complexes.
