Although good evidence has been found for ancbimerlc rmsistaace in the solvolytic reactions of unsaturated systems such as the 2-norbornen-~1 tosylates be,,/ kendo = 8 X 10')' and the 'I-isopropylidene 5-norbornen-2-yl tosylates', the smaller rate factor observed with saturated l ystomb such as the
The apparent substituent effect on the acetolysis of 2-arylethyl tosylates was analyzed as a sum of two linear substituent effect relationships for aryl-assisted and -unassisted processes. The effect on the former process satisfied the LArSR Eq. with a unique r value of 0.6.
