Although nitrene chemistry is promising for the light-induced modification of organic compounds, the reactivity of large polycyclic aromatic compounds and the effects of their curvature remain unexplored. Irradiation of azidocorannulene () in methanol/acetonitrile followed by HCl addition produced diastereomers and . Azirine is apparently trapped by methanol to form diastereomeric acetal derivatives that are hydrolyzed with HCl to yield and '.

However, in cryogenic matrices, the starting material typically re-forms before the radical pair diffuses apart. This study focused on N extrusion from an azido alkyl radical to prevent radical-pair recombination.

- The study examined the use of inhaled nitric oxide (iNO) for treating very preterm infants (born at 22 to 31 weeks) across 11 European countries from 2011 to 2012.
- Out of 7268 infants, 292 received iNO treatment, revealing significant variations in treatment rates between countries, with higher in-hospital mortality rates for those treated with iNO compared to matched controls.
- Despite the increased mortality during hospitalization, long-term follow-up of 5 years showed no significant risk of neurodevelopmental impairments in the survivors treated with iNO.
Solid-state photoreactions are generally controlled by the rigid and ordered nature of crystals. Herein, the solution and solid-state photoreactivities of carbonylbis(4,1-phenylene)dicarbonazidate () were investigated to elucidate the solid-state reaction mechanism. Irradiation of in methanol yielded primarily the corresponding amine, whereas irradiation in the solid state gave a mixture of photoproducts.

Its applicability to estimate neurodevelopmental outcomes in infants born extremely preterm (EPT; <28 weeks' gestation) is not well established.
Objective: To investigate the association between the Apgar score and neurodevelopmental outcomes in infants born EPT.
