摘要：

The effects of the substituent X on the homolysis rate constants (k(d)) of SG1-propionate type alkoxyamines (SG1-CHMeCOOX) are analyzed by a multiparametric equation with nu, the steric constant and sigma(1), the polar inductive/field Hammett constant of X. An influence of long-range polar and steric effects on k(d) was observed, that is, decrease in k(d) with increasing size of the X group and increase in k(d) with increasing polarity of the X group.
