Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

open access: yesAngewandte Chemie International Edition, EarlyView.
We report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.

Fluorine‐18 Fluorodeoxyglucose‐Positron Emission Tomography/Computed Tomography for Detection of Lymph Node Metastasis in Canine Mast Cell Tumour

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Lymph node (LN) metastasis has been associated with shorter survival times in dogs with mast cell tumour (MCT), and treatment of metastatic LN with lymphadenectomy or irradiation has been demonstrated to improve outcomes. Identification of metastatic LN in dogs with MCT is therefore of both prognostic and therapeutic significance.
