Triscyanocorrole, the Newest and Most Intriguing Member of the C-Substituted Corrole Family.

Considering the potential advantages of minimally sized corroles for diverse applications, this study reports a facile access to cyano-substituted derivatives via a rare CF/CN conversion. Investigation of the fully characterized gallium, phosphorus, and cobalt complexes discloses multiple effects of the meso-nitrile groups attached to the macrocycle. This corrole appears to be the most electron poor derivative which comes into play in the redox potentials of the corresponding complexes.

Co-occurrence of Traditional and Cyberbullying Victimization Among Adolescents: Characteristics, Psychological Difficulties, and Resilience.

This study examines whether students' experience of combined victimization, the experience of both traditional bullying and cyberbullying, is correlated with psychological difficulties. Additionally, the study examines whether Israeli students who cope with combined victimization differ in their resilience resources from students who experience solely traditional bullying, cyberbullying, or neither. Participants included 430 students aged 13-15 years from four Israeli schools who completed self-report questionnaires.

Redox Active Ligands for Catalyzing the Hydrogen Evolution Reaction.

Boron subphthalocyanines with chloride and fluoride axial ligands and three antimony complexes chelated by corroles that differ in size and electron-richness were examined as electrocatalysts for reduction of protons to hydrogen. Experiment- and computation-based investigations revealed that all redox events are ligand-centered and that the meso-C of the corroles and the peripheral N atoms of the subphthalocyanines are the largely preferred proton-binding sites.

Surprising Route to a Monoazaporphyrin and Full Characterization of Its Complexes with Five Different 3d Metals.

In the search for mild agents for the oxidative cyclization of tetrapyrromethane to the corresponding corrole, we discovered a route that leads to a monoazaporphyrin with three -CF groups. Optimization studies that allowed access to appreciable amounts of this new macrocycle paved the way for the preparation of its cobalt, copper, nickel, zinc, and iron complexes. All complexes were fully characterized by various spectroscopic methods and X-ray crystallography.
