The enthalpies of formation of lithium, sodium, potassium and thallium cyclopentadienyls were determined by reaction‐solution calorimetry as Δ f H ° [LiCp] = −76.5 ± 2.9 kJ/mol, Δ f H ° [NaCp] = −39.7 ± 2.5 kJ/mol, Δ f H ° [KCp] = −83.2 ± 3.2 kJ/mol, and Δ f H ° [TlCp] = +117.7 ± 1.9 kJ/mol. Using a previously developed model, the enthalpies of formation of RbCp and CsCp were estimated.
