Substituent effect on the solvolysis of α-t-butyl-α-methylbenzyl chlorides
摘要:
The substituent effect on the solvolysis rates of alpha-t-butyl-alpha-methylbenzyl chlorides in 80% aq. acetone was correlated to give p=-4.3 and r=0.91 in terms of the LArSR Eq. (1). This slightly reduced r value relative to full conjugation corresponds to a deviation by theta=24.5 degrees from the coplanarity of the benzylic pi-system.
