One‐Shot Pd(II)‐Catalyzed Multiple C–H Activation Enables Modular Construction of Fluorenylidene Oxindole‐Based Multi(Polycyclic) Aromatic Enes

Chemistry – A European Journal, EarlyView.
A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.

Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

Chemistry – A European Journal, EarlyView.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Everything Changed, Yet Hunting Rights Did Not: Formulation of Wildlife Property Rights in Postsocialist Slovenia

Environmental Policy and Governance, EarlyView.
ABSTRACT This study uses the policy regime framework to examine how background conditions, institutions, and actor configurations shaped hunting rights within the forest–wildlife policy domain during Slovenia's postsocialist transformation. Drawing on media analysis, in‐depth interviews with policymakers, and legislative documents, it conducts a ...

A location-aware revocation approach

, 2004
We present a new certificate revocation system for both on-line and off-line use, which is targeted to mobile-commerce systems. It allows to use certificates from any certificate issuer and to apply a proprietary revocation strategy. Our approach is well

Water Governance Under International Pressure: Policy Narratives, Food Security, Scarcity, and the Politics of Survival in Iran

Environmental Policy and Governance, EarlyView.
ABSTRACT Water governance is increasingly influenced by a paradox at the nexus of environmental scarcity and food security. Escalating water scarcity crises coincide with geopolitical disruptions that have exposed the fragility of global food supply chains, prompting states to expand domestic food production at the expense of water conservation ...
