This causes oxidativeaddition to become the rate-limiting step in the 1,10-phenanthroline-mediated reaction.
2
The immediate product of the oxidativeaddition step is found to undergo facile reductive elimination to provide the arylation product.
3
It is suggested that the formation of a T-shaped intermediate could foster the C-H activation via oxidativeaddition to the metal centre.
4
Because O-coordination of a deprotonated amino alcohol is favored over N-coordination in the oxidativeaddition transition state, O-arylation is favored with the 1,10-phenanthroline ligand.
