Divergent Synthesis of Möbius and Hückel N‐Heterocycloarenes From a Common Macrocyclic Backbone
Angewandte Chemie, EarlyView.In the divergent synthesis of Möbius and Hückel N‐heterocycloarenes from a common macrocyclic precursor, the annulation reaction dictates topology: Scholl reaction gives Möbius topology, while InCl3‐mediated alkyne annulation gives Hückel topology. The Möbius N‐heterocycloarene is unevenly contorted as revealed by crystal structure, and the Hückel N ...

Palladium‐Catalyzed Annulations of an Anti‐Bredt Olefin
Angewandte Chemie, EarlyView.We report metal‐catalyzed trappings of a [2.2.1]‐bridged bicyclic anti‐Bredt olefin (ABO). The methodology yields unusual heterocyclic products and is expected to prompt the further development of unconventional reactions, including metal‐catalyzed processes of ABOs and other strained olefins. ABSTRACT A famous class of alkene‐containing compounds that

Ciphertext policy attribute-based encryption scheme supporting direct revocation
Tongxin xuebao, 2016 In order to support fine-grained attribute revocation in direct revocation mode an attribute-based encryption scheme with efficient revocation was proposed.The model of ABE supporting attribute revocation was given,and a con-crete scheme was constructed ...

Practical group signature scheme with verifier-local revocation
Tongxin xuebao, 2011 An efficient approach of member revocation in group signature is verifier-local revocation.In this approach,revocation messages are only sent to signature verifiers,while signers have no involvement.There are some problems in group signature with ...

Transition Metal‐Free Heteroarene Insertion Into C─C Bonds of Benzocyclobutenones
Angewandte Chemie, EarlyView.A transition metal‐free insertion of five‐membered heteroarenes into the C─C bonds of benzocyclobutenones has been achieved under mild and operationally simple conditions. This method provides an efficient and modular approach to access fused partially saturated hetero‐polycyclic scaffolds that exist in many bioactive molecules.

Revocation and Retribution [PDF]
, 2021 Revocation of community supervision is a defining feature of American criminal law. Nearly 4.5 million people in the United States are on parole, probation, or supervised release, and 1/3 eventually have their supervision revoked, sending 350,000 to ...

Iterative Synthesis of Pyrene–Coronene Molecular Graphene Nanoribbons
Angewandte Chemie, EarlyView.An iterative approach delivers a new family of undoped, cove‐edged graphene nanoribbons with lengths up to 9.1 nm that exhibit both molar absorptivity and fluorescence brightness values on the order of 105 M−1 cm−1 and an intrinsic charge‐carrier mobility of 475 ± 32 cm2 V−1 s−1.

Revocation Games in Ephemeral Networks [PDF]
A frequently proposed solution to node misbehavior in mobile ad hoc networks is to use reputation systems. But in ephemeral networks - a new breed of mobile networks where contact times between nodes are short and neighbors change frequently ...
