Energies of homolytic cleavage of O-H bonds in 33 compounds of the gen
eral formula RO(n)H (n = 2, 3, and 4) were calculated by the AM1 metho
d. For hydrotrioxides and hydrotetroxides, the bond dissociation energ
ies are virtually independent of the nature of the substituent R: D(RO
(n)-H) = 92.3+/-0.8 kcal mol(-1) (n = 3 and 4).
