1,6-addition versus 1,6-substitution
« on: March 07, 2014, 04:46:44 PM »
Hi. The question is about radical attack of tBu-radical into para-position of benzophenone ketyl (2nd product in 1st attached file).

I do not understand where para-hydrogen has gone? Lithium hydride :o?

Source: Yamataka et al. , JOC, 1989, 54, 4706

The reference #7 is  Crossland et al, Acta Chem. Scand., 1971,  25, 1158 , where the products are non-aromatic(see the 2nd attachtment).
