Recurring Chains Following Addition of Atomic Hydrogen to Acetylene

Article abstract of DOI:10.1021/j100405a036

The C2H3 radical was prepared by attachment of H atoms to C2H2.Complex chain reactions ensue: C2H3 + H2 -> C2H4 + H; C2H3 + C2H2 -> C4H5; C4H5 + H2 -> C4H6 (1,3-butadiene) + H; C4H5 + C2H2 -> C6H6 + H (cis addition); C4H5 + C2H2 -> C6H7 (trans addition); C6H7 + H2 -> C6H8 (trans-1,3,5-hexatriene) + H; C6H7 + C2H2 -> C8H9 (leading to higher members).Relative coefficients are derived from product ratios, and the system has been closely matched with a model scheme.The products of the mutual termination reaction of two C2H3 radicals have been investigated.
