Carbonyl hydrate, hydroperoxide

Carbonyl group, nucleophilic addition cychzation, 230, 233, 245-52, 253 Carbonyl hydrate, hydroperoxide hydrogenolysis, 156 Carbonyl oxides... 

The gas phase enthalpy of reaction 6 for bis(hydroxymethyl) peroxide is — 192 kJ mol , which deviates from the other hydrate-producing peroxides by nearly 89 kJ mol . The enthalpy of reaction 8, 145 kJmol, is likewise discrepant by some 120 kJmol from that for diethyl peroxide, ca 26 kJ mol. From the high-level calculations reported in Reference 28, the reaction enthalpy for the addition of H2O2 to formaldehyde is —59 kJ mol. A similar reaction is equation 10 for the gas phase addition of tert-butyl hydroperoxide to a carbonyl group.
