We derive the structural principles of polyhedral allotropes of phosphorus, introducing three distinct families of black phosphorus nanostructures. The predicted tetrahedral, octahedral, and icosahedral phosphorus cages can also be considered as phosphorus fullerenes. Phosphorus cages up to P(888) are systematically investigated by quantum chemical methods, and their thermodynamic stabilities a...

The aerobic direct dehydrogenative annulation of N-iminopyridinium ylides with terminal alkynes leading to pyrazolo[1,5-a]pyridine derivatives has been developed.

BACKGROUND Elevated plasma cardiac troponin, elevated plasma phosphorus and decreased plasma vitamin D have been shown to be associated with negative outcomes. METHODS AND RESULTS Troponin I, calcium, phosphorus and 25-OH vitamin D were studied in a cohort of 60 patients with stable coronary heart disease and preserved left ventricular function. Using a cut-off value of 0.012 ng/mL for plasma...

Two phosphaalkene radical cations 1(•+) and 2(•+) have been reported. 1(•+) is stable in the solid state and has been structurally characterized. 2(•+) only remains persistent in solution. 1(•+) is described as a phosphorus-centered radical, while 2(•+) as a delocalized radical with little contribution from phosphorus.

Black phosphorus is considered a very promising semiconductor for two-dimensional field-effect transistors. Initially, the main disadvantage of this material was thought to be its poor air stability. However, recent studies have shown that this problem can be solved by suitable encapsulation. As such, long-term studies of the outstanding properties of black phosphorus devices have become possib...

A heating-induced desulfurization annulation of readily available CF3-imidoyl sulfoxonium ylides and isothiocyanates for the construction 2-trifluoromethylquinolines has been achieved. The developed transformation was performed under metal- additive-free conditions, producing a variety biologically valuable 2-trifluoromethylquinoline derivatives with high efficiency.
