AbstractThe laser‐ion beam photodissociation for [C4H4]+˙ ions produced from a variety of precursors has been studied. Based on the data it is apparent that two structurally distinct forms of the [C4H4]+˙ ion are produced by fragmentation of larger systems. The relative population of the various structural forms is very dependent on the internal energy of the fragmenting ion, with 1‐buten‐3‐yne [C4H4]+˙ ions being favored at low internal energies. As the internal energy of the reactant ion is increased, the relative population of butatriene [C4H4]+˙ ions increases. The laser‐ion beam photodissociation technique is able to selectively sample these two structural forms.
Deuteration and Dimerization of Acetylene with a Nieuwland Catalyst in Deuterium Oxide
Efficient deuteration and dimerization of acetylene have been readily attained in deuterium oxide with a Nieuwland catalyst which is practically used for dimerization of acetylene.
