The photoreducing ability of these compounds was probed in the dehalogenation of aryl halides, initially using methyl 4-chlorobenzoate (Ered = -1.98 V in DMF vs SCE) as a model substrate. Reaction yields were determined by GC-MS; the PCs were not detectable using this method. Replicating closely the conditions of Discekici et al., namely MeCN as solvent, NBu3
