Zn(OTf)2‐Catalyzed Dehydrocoupling of Terminal Alkynes with Diisopropylaminoborane: A Modular Route to Mono‐ and Dialkynylboranes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 10, 19 May 2026.
We report a Zn(OTf)2‐catalyzed dehydrocoupling of terminal alkynes with diisopropylaminoborane (DIPOB), which enables the selective synthesis of mono‐ and dialkynylboranes under mild conditions. This method provides a versatile platform for accessing stable tetracoordinate alkynylborons while effectively suppressing hydroboration side reactions.

Steric Hindrance and Secondary Interactions Govern Reconfiguration Between Two Complex CuI Coordination Cages

open access: yesAngewandte Chemie, Volume 138, Issue 21, 18 May 2026.
Fine‐tuning steric and C─H···π contacts directs assembly of two CuI cages. An identical naphthylene‐based subcomponent forms a [CuI12L6]12+ pseudo‐hexagonal prism stabilized by 29–32 C─H···π contacts and 12 arene stacking pairs with 6‐methyl‐2‐formylpyridine, whereas the 3‐methyl analog imparts steric clashes, yielding a [CuI8L4]8+ open prism ...

Development of a Cu‐Catalyzed Regioselective Hydrazidation of 1,2‐Diborylalkenes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 10, 19 May 2026.
Alkene 1,2‐diboronate esters undergo a Cu‐catalyzed regioselective addition to azodicarboxylates to generate functionalized borylated hydrazides. An investigation of mono‐ versus di‐hydrazidation processes and the use of these products in synthesis are described.
