WebAbstract Supersonic molecular Jet laser time of flight mass spectroscopy (TOFMS) is employed to determine the minimum energy conformation of the allyl group with respect to the benzene ring of allylbenzene, 1-allyl-2-methy]benzene and 1- allyl-3-methylbenzene. WebIn this contribution, the issue of low activity (0.04–12.1 kg mol −1 h −1) is overcome by the use of polar allylbenzene as the polar allyl monomer. Under the activation of NaBArF, the classic α-diimine Pd( II ) catalyst 1 [(Dipp-N C(Me)–C(Me) N-Dipp)PdMeCl] was inert to the copolymerization of ethylene and polar allylbenzene monomers.
