The homolytic liquid-phase reactions of N,N-dimethylaminodialkoxymethanes, initiated by tert-butoxyl radicals in the range of 120-150 deg C, were investigated.The mechanism of the unbranched chain process of fragmentation of the acetals with quadratic chain termination at the alkyl radicals was determined.As a result the corresponding dimethylcarbamic esters, dimethylformamide, alkanes, and carbonyl compounds were formed.The relative rate constants for the transformations of the nitrogen analogs of the ortho esters were calculated.The difference in the activation energies for the cleavage of the C-H bonds adjacent to one and three heteroatoms was determined for N,N-dimethylaminodimethoxymethane (ΔE=5 kcal/mole) and N,N-dimethylaminodipentyloxymethane (ΔE=8 kcal/mole).
