摘要

The acetolysis of the primary tosylates, N-methyl-N-nitroso-2-(tosyloxy) ethylamine (1) and N- methyl-N-nitroso-3-(tosyloxy) propylamine (2), gives the corresponding acetates in better than 80% isolated yields. The kinetic analysis of the acetolysis reactions indicated very rapid solvolysis. The activation parameters for 1 are 0= 17 kcal/mol and AS $=-16.6 eu, and for 2 they are 0= 18.5 kcal/mol and AS*=-21 eu. Acetolysis of the optically active secondary ...
