    • The activation energy for the β C-H scission b n•/zn• → bn/zn, H• (Scheme 1b) is ∼200 kJ/mol, while that for the β C-C bond scission b n•/zn• → bn-1•/zn-1 •, C8H8 (monomer loss) is ∼80 kJ/mol; dissociation of bn•/zn • via backbiting and subsequent β C-C bond scission to yield bn-3•/zn-3 •, an-2/yn-2, K3, or J2• (Scheme 1c) also requires ∼80 kJ/mol.17 The activation energies for the competitive β scissions an•/yn
