“…Further kinetic studies on the thermal decomposition of two other Phydroxy ketones, i.e., 4-hydroxy-3-methyl-2-pentanone and 4-hydroxy-2-pentanone, in xylene solutions [2] was aimed at examining the influence of substituted methyl group on the mechanism and velocity. The results obtained from these reactions, in xylene solutions, suggested a n agreement with the mechanism proposed for the reaction in the gas phase as described above (eq.…”

“…Experimental and/or theoretical studies of the thermolysis reaction of b-hydroxy derivatives [4][5][6][7][8][9][10][11][12][13][14][15], and specially b-hydroxynitriles [5,9] have been carried out for some of us. In a recent work [16], we have published the results obtained from a calorimetric and computational study of the thermochemistry of 3-buten-1-ol and 3-butyn-1-ol concluding that the weak intramolecular hydrogen bond from the OH hydrogen to the p-bond charge cloud that exists in both compounds has not significant influence on the enthalpy of formation of these species.…”

“…It has previously been observed that [6] in m-xylene solutions at 553 K, β-hydroxyketone and 4-hydroxy-4-methyl-2-pentanone pyrolyze 134 times more rapidly than do the analogously substituted β-hydroxy ester: ethyl-3-hydroxy-3-methylbutanoate pyrolyzes 2170 times more rapidly than do methyl-3-hydroxy-3-methylbutanoate. The proposed mechanism is consistent with the greater difficulty in the formation of enol from esters than from ketones [11] (see Fig.…”
