Examined are the kinetics of free radical liquid-phase transformation of diethoxymethane, dideuterodiethoxymethane, di(pentadeuteroethoxy)methane, dideuterodi(pentadeuteroethoxy)methane, and di(1,1-dideuteroethoxy)methane initiated by the thermal decomposition of t-butyl peroxide at 130/sup 0/C. Results show conclusively that the fundamental direction of the free radical attack on the acetal molecule is at the carbon-hydrogen bond in the vicinity of the 2 oxygen atoms. The introduction of deuterium into the other fragment of the molecule does not have any significant effect on its subsequent activity. 5 references, 1 table.
