XRD analysis revealed the formation of a "trimer" and a benzo[f][1,2,4]triazepine via a novel mechanism. The latter is formed from the anion generated from the isolated radical, which suggests its instability in organic batteries.}, journal={CHEMICAL COMMUNICATIONS}, author={Obijalska, Emilia and Pietrzak, Anna and Constantinides, Christos.

The intermediate anion is also trapped as an N-benzyloxycarbonyl derivative and purified prior to deprotection and oxidation to the radical. The method was demonstrated for nine (het)arenes, and the regioselectivity of nucleophilic addition to the benzo[e][1,2,4]triazine and trapping of the intermediate anion with electrophiles was assessed computationally.}, number={5}, journal={ORGANIC LETTERS}, author={Constantinides, Christos P. and Obijalska, Emilia and Kaszynski, Piotr}, year={2016}, month={Mar}, pages={916–919} } @misc{constantinides_koutentis_2016, title={Stable N- and N/S-rich heterocyclic radicals: Synthesis and applications}, volume={119}, journal={Heterocyclic chemistry in the 21st century: a tribute to alan katritzky}, author={Constantinides, C.

Planarization of 1 results in bathochromic shift to the near-IR region, greater spin delocalization, and anodic shift of the reduction potential only for 1S . Magnetization studies revealed nearly ideal paramagnetic behavior at high temperatures for both radicals 1S and 1O with one-dimensional ferromagnetic interaction in the former (2J=14.4 cm(-1) ) and antiferromagnetic interactions in 1O at low temperatures.}, number={37}, journal={ANGEWANDTE CHEMIE-INTERNATIONAL EDITION}, author={Kaszynski, Piotr and Constantinides, Christos P. and Young, Victor G., Jr.}, year={2016}, month={Sep}, pages={11149–11152} }
