Kinetic studies were carried out on the aminolysis of propargyl and 1-methylpropargyl arenesulphonates in acetonitrile at 45.0 deg C.The cross-interaction constants, ρxz and βxz, are similar to, but smaller than, those for the SN2 processes at other primary and secondary carbon centers.Compared with the allyl series, the smaller magnitude of ρxz and βxz reflects a looser transition state, which in turn leads to a lower rate despite the greater Taft's ?* value and the lower intrinsic (ΔE0) and thermodynamic barriers (ΔE0).
