Difluoromethylenation of Alkynes: Streamlined Access to Allyl Difluorides
Angewandte Chemie, EarlyView.Stabilizing primary oxocarbenium in HF/pyridine unlocks a direct alkyne difluoromethylenation – an efficient route to synthetically‐relevant allyl difluorides in a single step. ABSTRACT A direct difluoromethylenation of alkynes has been developed using HF/pyridine as a dual acidic and fluorinating medium. The reaction proceeds via in situ generation of

Katalyse durch einen metastabilen, photoschaltbaren Käfig
Angewandte Chemie, EarlyView.Ein selbstassemblierter heteroleptischer Käfig entsteht durch die Isomerisierung eines photoschaltbaren Liganden in seine metastabile Z‐Isomerform (Z‐1) unter Einwirkung von grünem Licht, kombiniert mit einem nicht schaltbaren Liganden 2 und Palladium(II)‐Ionen.

Angewandte Chemie, EarlyView.Catalytic, intramolecular N‐heterocycle arylation by nucleophilic aromatic substitution (SNAr) is now available for synthesis of highly strained macrocycles and medium‐sized heterobiaryl atropisomeric rings, including atropopeptides. Key to the approach is the ability to generate a strong base catalytically, taking advantage of base‐embedding ...

1,2‐Bis(boronate) Arenes by Borylation Directed Borylation
Angewandte Chemie, EarlyView.Boron electrophiles derived from tetrabromo‐pyrazaboles and AlCl3 affect the regioselective vicinal double C–H borylation of a range of arenes and polycyclic aromatic hydrocarbons (PAHs). A subsequent pinacol installation step then affords the vicinal bis‐boronate ester‐substituted arene/PAH.

Angewandte Chemie, EarlyView.Die Click‐Chemie hat sich von dem Aufbau kovalenter Bindungen hin zum Spalten von Bindungen weiterentwickelt. Hier wird über einen Kaskaden‐Aufbau berichtet, der diese Verfahren kombiniert, um multifunktionale biomolekulare Gerüste in einer modularen Ein‐Topf‐Reaktion aufzubauen.

Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical
Angewandte Chemie, EarlyView.We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐
