Dehalogenation of brominated versus iodinated precursors and occurrence of organometallic intermediates for different metal surface.

metal	Bromine cleavage	Iodine cleavage
Cu(111); organometallic → disordered	Full @ RT	Full @ RT
Ag(111); organometallic → ordered	Partial @ RT; Full @ ~150°C	Full @ RT
Au(111); rarely organometallic intermediates	None @ RT; Full @ ~180°C	Full @ RT
