## l+-Phenylalky1 )-1-tifluoromethylbenzyl cations and the a-CH,-substituted analogues were generated from the corresponding protonated benzyl alcohols by loss of H,O during chemical ionization (CI). The unimolecular reactions of these ions and of their derivatives specifically deuterated at the 1
The copper-catalyzed cross-coupling reaction of ␣-selenoacylzirconocene chloride 3 with haloalkynes in the presence of carbon monoxide gives ␣seleno-substituted vinyl alkynyl ketones 5 in moderate yields. The reaction conditions are neutral and mild enough (room temperature, 1 atm carbon monoxide) t
