Aromatic Nitration
« on: March 03, 2012, 10:21:19 AM »
Q: What are X and Y?

Ain't getting the right logic for the product Y. (i.e., where should the nitration occur?)

nitration will take place on the ortho or para position to the two substitutents on the aromatic ring.The ortho positions are most hindered and hence para is the best position for the nitration

The acid may be to cause isomerization of the cyclophane. Possibly to the para form?

Then nitrate as normal, ortho-para direction.

I found this one odd. Maybe look at Allinger et al, J. Am. Chem. Soc., 1961, 83 (8), pp 1974–1978
