₁H NMR yield for β-β and β-O coupling products using four chemical oxidants


Entry	Oxidant	% 1b_^a	% β-O coupling_^a	% β-β coupling_^a
1	tert-butyl hydroperoxide (70% in H₂O)	trace	28	28
2	(NH₄)₂S₂O₈	10	12	trace
3	iodosobenzene	10	12	52
4	H₂O₂ (30% in H₂O)	30	20	32

Yields determined by ₁H NMR spectroscopy of the reaction mixture with CH₂Br₂ as internal standard.
