An interesting trend is that in the isostructural series of 1,2,5-chalcogenadiazoles and their benzo-fused derivatives (chalcogen: S, Se, Te) the molecular EA increases with atomic number of the chalcogen, i.e. , from S to Te despite the fact that atomic EA and Allen electronegativity decreases in this sequence as 2.08 (S), 2.02 (Se) and 1.97 (Te) eV, and 2.59 (S), 2.42 (Se) and 2.16 (Te), respectively.

It is worthy of mention that although relatively less yields of coupling products with aryl chlorides have been obtained compared to aryl bromides as substrates, these results are still quite significant, as they represent successful examples of the Suzuki-Miyaura reaction of activated aryl chlorides at room temperature using environmentally-benign reaction media.

It is interesting to note that even though the crude extract did not show notable activity against Tbr , several of the spCCC subfractions displayed such activity at quite significant levels, e.g., subfraction E9 with an IC 50 value 0.13 μg/mL against Tbr and an SI of 38.
Despite this, data show a clear trend with increasing amounts of O-containing groups in the carbon anodes exposed to light indicating that the carbon material is slightly oxidized ( Table 2 ); this is more remarkable in the amount of CO 2 desorbed, associated with the decomposition of carboxylic-like groups.
