Observations on the enforced orthogonality concept for the synthesis of fully hindered biaryls by a tin-free intramolecular radical ipso substitution

Hindered biaryls have been simply prepared using diazonium salt precursors and an intramolecular free radical [1,5] ipso substitution protocol. The introduction of an additional substituent ortho to the diazonium group in the σ aryl radical donor further enforces the formation of ipso substitution products and hence fully hindered biaryls are the favoured products.
