Abstract

The α-C–H bond dissociation enthalpy (BDE) in tetralin (1,2,3,4-tetrahydronaphtalene) was determined using time-resolved photoacoustic calorimetry as 357.6 ± 5.4 kJ mol−1. This value is some 10 kJ mol−1 higher than the only previous experimental determination but in remarkably good agreement with the α-C–H BDEs in the structurally related compounds such as 1-butene, cyclohexene, and ethylbenzene.
