, p. 1534 - 1535 (1980)
Carbanions of α-phenoxy and thioalkoxy nitriles substitute hydrogen in the para or ortho position of aromatic nitro compounds, giving nitroarylacetonitriles in a process in which phenolate or thiolate anions are vicarious leaving groups.

A new A-D-A small molecule (SM) based on a 3,6-dithienylcarbazole donor unit at the center and nitrophenyl acrylonitrile acceptor units as the terminal ends was synthesized by the Pd catalyzed Stille coupling reaction for application as a donor material in the organic bulk heterojunction solar cells. The SM possesses a low lying HOMO energy level at -5.34 eV and optical band gap of 1.74 eV. The photovoltaic performance of the SM was investigated with PC 60BM and PC70BM as acceptors cast from THF with 3% CN additive and without additive. The power conversion efficiency (PCE) of the organic solar cells based on SM:PC60BM cast from THF solvent reached 1.94% with a high Voc of 0.94 V, a Jsc of 6.08 mA cm -2 and FF of 0.34, where as the PCE of SM:PC70BM cast from THF solvent was 2.65% with a Voc of 0.96 V, a Jsc of 7.26 mA cm-2 and FF of 0.38%, under the illumination intensity of 100 mW cm-2. The higher PCE of the organic solar cells based on PC 70BM as an electron acceptor has been attributed to its strong absorption in the visible region than PC60BM. The PCE of the organic solar cells has been further improved to 3.76% and 4.96% for SM:PC 60BM and SM:PC70BM, respectively, cast with CN-THF solvent. The Royal Society of Chemistry 2013.

A photoinduced iron-catalyzed ipso-nitration of aryl halides with KNO2 has been developed, in which aryl iodides, bromides, and some of aryl chlorides are feasible. The mechanism investigations show that the in situ formed iron complex by FeSO4, KNO2, and 1,10-phenanthroline acts as the light-harvesting photocatalyst with a longer lifetime of the excited state, and the reaction undergoes a photoinduced single-electron transfer (SET) process. This work represents an example for the photoinduced iron-catalyzed Ullmann-type couplings.
