“…As first mentioned by Hoffmann in 1968, oxyallyl derivatives have been postulated as intermediates in an umber of rearrangements and cycloaddition reactions [30] such as the Favorskii rearrangement [31] and the photochemical rearrangemento f cyclohexadienones. [32] Although the parent oxyallyl compounds are too elusive to isolate, [33] an umber of oxyallyl derivatives have been synthesized by involvingt ransition-metal complexes [34] and electron donors such as NHCs. [22b, 35] However, transiento xyallylr adical cations have been observed by EPR spectroscopy in ag lassy matrix at 77 Ka nd by mass spectrometry.…”

Over the past decade, numerous stable organic and main-group radicals have been synthesized from N-heterocyclic carbenes (NHCs). The structure of NHCs, in particular, offers electronic stabilization that helps to delocalize the unpaired electron over the molecule. In addition, the sterically bulky substituents of NHCs protect the radical center to prevent detrimental reactions such as dimerization. These advantages enable the straightforward synthesis and characterization of various interesting organic radicals starting from NHCs, which are, these days, widely available. NHCs have enabled the structural characterization of various organic radicals over the past decade, including α-carbonyl, propargyl, oxyallyl, and triazenyl radicals as notable examples. This minireview summarizes the advances in this field, mainly focusing on the preparation and stability as well as the properties and applications of NHC-derived organic radicals.

“…Starting from the early works of Rundle 1988 andBenites 1996, the concept of physics-based simulators became popular during the last decade, due to their ability to model and reproduce long earthquake occurrence records (ranging from thousands to millions of years). Thus, a large number of such algorithms have been proposed (e.g., Yikilmaz et al, 2010;Richards-Dinger and Dieterich, 2012;Ward, 2012;Schultz et al, 2017) and applied (e.g., Robinson et al, 2011 andChristophersen et al, 2017 in New Zealand;Shaw et al, 2018 in California).…”

Strong Earthquakes Recurrence Times of the Southern Thessaly, Greece, Fault System: Insights from a Physics-Based Simulator Application

et al. 2021

The recurrence time, Tr, of strong earthquakes above a predefined magnitude threshold on specific faults or fault segments is an important parameter, that could be used as an input in the development of long-term fault-based Earthquake Rupture Forecasts (ERF). The amount of observational recurrence time data per segment is often limited, due to the long duration of the stress rebuilt and the shortage of earthquake catalogs. As a consequence, the application of robust statistical models is difficult to implement with a precise conclusion, concerning Tr and its variability. Physics-based earthquake simulators are a powerful tool to overcome these limitations, and could provide much longer earthquake records than the historical and instrumental earthquake catalogs. A physics-based simulator, which embodies known physical processes, is applied in the Southern Thessaly Fault Zone (Greece), aiming to provide insights about the recurrence behavior of earthquakes with Mw ≥ 6.0 in the six major fault segments in the study area. The build of the input fault model is made by compiling the geometrical and kinematic parameters of the fault network from the available seismotectonic studies. The simulation is implemented through the application of the algorithm multiple times, with a series of different input free parameters, in order to conclude in the simulated catalog which showed the best performance in respect to the observational data. The detailed examination of the 254 Mw ≥ 6.0 earthquakes reported in the simulated catalog reveals that both single and multiple segmented ruptures can be realized in the study area. Results of statistical analysis of the interevent times of the Mw ≥ 6.0 earthquakes per segment evidence quasi-periodic recurrence behavior and better performance of the Brownian Passage Time (BPT) renewal model in comparison to the Poissonian behavior.
