Benzo[cd]azulenyl: A Structural Isomer of Phenalenyl—Synthesis and Properties of Its Tri‐tert‐butyl‐substituted Derivative and Formation of a Thermal‐ and Photoresponsive σ‐Dimer

open access: yesChemistry – A European Journal, EarlyView.
Benzo[cd]azulenyl, a nonalternant isomer of phenalenyl, is identified as a new member of the nonalternant hydrocarbon radical family. The tri‐tert‐butyl substituted derivative forms a stable σ‐dimer in the solid state. Upon exposure to external stimuli such as light and heat, the σ‐bond of the dimer dissociates, producing the monomeric radical.

Photoinduced Hydrogenative Dearomatization With Homocoupling of Quinolines to Construct Octahydro‐4,4'‐biquinolines

open access: yesChemistry – A European Journal, EarlyView.
Dearomative homocoupling of quinolines into 1,1',2,2',3,3',4,4'‐octahydro‐4,4'‐biquinoline (OHBQ) is reported. The photoexcited boron complex, in situ generated from quinoline, HB(pin), and KOtBu, enables the unprecedented homocoupling of tetrahydroquinolines that is challenging in the ground state, expanding the chemical diversity of OHBQ derivatives.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Igreja Católica e revolução na América Central – quebra de paradigma na Nicarágua

open access: yesRevista Conjuntura Austral, 2016
Nessa pesquisa verificaremos a influência da experiência nicaraguense na quebra do paradigma segundo o qual a religião e os atores religiosos estariam associados mais à conservação do staus quo do que à sua ruptura.

Photoinduced Copper‐Catalyzed para‐Selective C–H S‐Arylation of Benzylic Oxime Carbonates with Sulfenamides

open access: yesChinese Journal of Chemistry, EarlyView.
We present a dual copper/photoredox catalytic system that enables the para‐selective C–H functionalization of benzyl alcohols with sulfenamides. This approach facilitates the para‐selective C–H sulfilimination of benzylic oxime carbonates through an orchestrated sequence involving photoinduced decarboxylation/dearomatization of oxime carbonates, copper‐

Efficiency and Perceptions in Public CSR: An Integrated Efficiency–Perception Analysis of Spanish Defence Delegations

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Public organisations often experience a discrepancy between improvements in technical efficiency and stakeholders' perceptions of integrity and performance. This study analyses the mechanisms that may underlie this efficiency–perception discrepancy in Spanish Defence Delegations during 2020–2023.
