Optically active benzyl-α-d alcohols have been synthesized in up to 89percent ee by asymmetric hydrogenation of benzaldehyde-α-d and its derivatives catalyzed by BINAP-Ru(II) complexes.A remarkable enhancement in enantioselectivities has been observed for
Free 1-Phenylallyl Cations in the Aromatisation of Dihydronaphthalenes by Triphenylmethyl Tetrafluoroborate

The aromatisation of 1,2- and 1,4-dihydronaphthalenes by trityl cations proceeds by a common intermediate, the 1-phenylallyl cation 4 of sufficient lifetime to allow for both side reactions and loss of stereoselectivity.The primary hydride abstraction occurs with moderate tunneling participation and in a linear geometry of the three participating atoms as shown by the temperature dependence of the primary isotope effect.
