Question

Why tosyl group is better leaving group than benzenesulphonyl group?

Answer 1

hey mate here ur answer

I read a book on organic chemistry that stated that tosyl is better leaving group than benzenesulphonyl group, but it gave no reason for comparison. I think that benzenesulphonyl should be better leaving group since methyl group in tosyl should be destabilizing for the anion due to its +I and +R effect. I tried searching on the internet but it was of no help. Please give a reason why tosyl is better leaving group.
