Alcohol‐Directed Carboamination of Conjugated Enynes

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
The first general three‐component intermolecular Pd‐catalyzed carboamination of conjugated enynes enables the coupling of anilines and aryl triflates to produce functionalized allenic amines, utilizing a native alcohol directing group to control regioselectivity.

Site‐Selective B─H Activation via HAT Toward Xanthyl‐closo‐Carboranes as Bench‐Stable Precursors of Organosulfur Boron Clusters

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
A light mediated direct regioselective B─H functionalization, via hydrogen atom transfer (HAT), is described. Unexplored xanthyl‐closo‐carboranes as novel bench‐stable and versatile platforms to access sulfur‐containing boron clusters are reported for the first time.
