Stereochemistry of Bromine Addition to an Alkene - …
This is consistent with the proposed chain mechanism in in which a liberated Br· produced in the reduction of -1,2-dibromo-1,2-diphenylethane can abstract a hydrogen from the amine to yield an α-amino radical, which can in turn propagate the chain ().

Proposed Catalytic Cycle and Chain Reaction for the Reductive Dehalogenation of -1,2-Dibromo-1,2-diphenylethane Using Cationic Organic Photosensitizers
(-1,2-Dibromo-1,2-diphenylethane is sparingly soluble in DMF; however, as the reaction proceeds, it becomes fully homogeneous.) The reaction was purged with argon for 15 min, followed by 5 min of irradiation with two warm-white LEDs.
