Straightforward Formation of Borirenes from Boroles and Dialkynes Open
We report a selective one‐step synthesis of perarylated borirenes by reaction of antiaromatic boroles with 1,4‐diarylbuta‐1,3‐diynes. Mechanistic studies, both experimental and computational, reveal key intermediates, including boranorborn…

Synthesis and reactivity of a parent phosphathioethynolato-borane and a boraarsaketene Open
The first main group phosphathioethynolates, [LBH 2 (SCP)] (L = carbene), combine phosphaalkyne, sulfide and hydroborane reactivity to generate complex B,P,S-polyheterocycles, while [LBH 2 (AsCO)] leads to a rare arsinidene–alkene π comple…

Experimental Observation of a Terminal Borylene‐Dinitrogen Adduct via Cleavage of a 1,2,3,4,5‐Diboratriazoline Open
While azides do not react with simple alkenes except under harsh conditions, a diboron alkene analogue, the doubly cyclic alkyl(amino)carbene (CAAC)‐stabilized dicyanodiborene 1 , reacts spontaneously with organic azides (7–10 equiv.) at r…

Bypassing Ammonia: From N<sub>2</sub> to Nitrogen Heterocycles without N<sub>1</sub> Intermediates or Transition Metals Open
Diboradiazene compounds, derived in one step from the boron‐mediated reduction of dinitrogen (N 2 ), were treated separately with sulfur and acetic anhydride, providing heterocyclic compounds that are BN isosteres of thiophene and 1,3‐oxaz…

Synthesis and Reactivity of Tricoordinate Organoberyllium Azides Open
A series of terminal mono‐ and disubstituted beryllium azides of the form [(CAAC)Be(N 3 )R] (R=CAACH, Dur; CAACH/CAAC=1‐(2,6‐di iso propylphenyl)‐3,3,5,5‐tetramethylpyrrolidin‐2‐yl/idene, Dur=2,3,5,6‐tetramethylphenyl) and [L 2 Be(N 3 ) 2 …

Synthesis and Reactivity of a Dialane‐Bridged Diradical Open
Radicals of the lightest group 13 element, boron, are well established and observed in numerous forms. In contrast to boron, radical chemistry involving the heavier group 13 elements (aluminum, gallium, indium, and thallium) remains largel…

Peter Paetzold (1935–2023): a Chemist of Many Talents Open
Peter Paetzold passed away on August 17, 2023 in Aachen, Germany. One of the great pioneers of low-valent boron and boron cluster chemistry, he will also be remembered for his outstanding teaching and the passion he brought to all of his m…
