Photoisomerization: N-phenylcarbazole-conjugated dimethyl 2,3-diethynylfumarate/maleate, E/Z-4, shows highly efficient and reversible visible-light E/Z photoisomerization (φtotal=0.40) upon excitation with an intramolecular charge-transfer band. This photochromism induces switching of electronic communication between the two N-phenylcarbazole moieties in the one-electron oxidized mixed-valent state (see scheme). Copyright

CuBr was found to be an efficient catalyst for the C-N cross coupling reaction of purine and diaryliodonium salts. 9-Arylpurines were synthesized in excellent yields with short reaction times (2.5 h). The method represents an alternative to the synthesis of 9-arylpurines via Cu(ii) catalyzed C-N coupling reaction with arylboronic acids as arylating agents. The Royal Society of Chemistry 2011.
