TL;DR: Reaction of the 1,2,3-triazene Tol−NN−NH−Tol with bases Li(N(SiMe3)2, n-BuLi, KH, K(N (SiMe 3)2), and KO-t-Bu results in deprotonation of the triazene to give the lithium and potassium triazenide complexes.
Abstract: Reaction of the 1,2,3-triazene Tol−NN−NH−Tol with bases Li(N(SiMe3)2, n-BuLi, KH, K(N(SiMe3)2, and KO-t-Bu results in deprotonation of the triazene to give the lithium and potassium triazenide complexes. Both have been characterized structurally and have a dimeric core. However, the bonding of the triazenide to the metals is very different.

TL;DR: Silyl-substituted NHC 2 reacts easily with 1-azidoadamantane to form triazene 3, in which the exocyclic C=N bond is slightly shorter than those of regular NHC-derived triazines.
Abstract: Reaction of IPr x SiCl(2) (1) [IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene] with 1-azidoadamantane leads to functionalized N-heterocyclic carbene (NHC) 2. Silyl-substituted NHC 2 reacts easily with 1-azidoadamantane to form triazene 3, in which the exocyclic C=N bond is slightly shorter than those of regular NHC-derived triazines. 2 could serve as a promising ligand for transition metals.

TL;DR: Variable-temperature NMR studies were carried out using 15N-labeled triazene complexes prepared from the 1,3-Ph15N=N15N(H)Ph ligand and the X-ray crystal structure determination of the OsH(PhN=NH){PPh(OEt)2}4]BPh4 complex is reported.
Abstract: Triazenide [M(η2-1,3-ArNNNAr)P4]BPh4 [M = Ru, Os; Ar = Ph, p-tolyl; P = P(OMe)3, P(OEt)3, PPh(OEt)2] complexes were prepared by allowing triflate [M(κ2-OTf)P4]OTf species to react first with 1,3-Ar...

TL;DR: Triazene-substituted arylboronic esters were prepared readily from the corresponding aryL magnesium derivatives and shown to function as a new class of donor-acceptor-subStituted coupling reagents.
Abstract: Triazene-substituted arylboronic esters were prepared readily from the corresponding aryl magnesium derivatives and shown to function as a new class of donor–acceptor-substituted coupling reagents. The selective functionalization of these aromatic derivatives led to a wide variety of terphenyl derivatives in which the original bifunctional unit (often further substituted with another functional group) formed the central aromatic ring. The functionalized terphenyl derivatives were formed in two efficient cross-coupling steps from the triazene-substituted boronic esters: Suzuki cross-coupling with an aryl halide was followed by BF3⋅OEt2-induced palladium-catalyzed coupling of the diazonium salt generated in situ from the triazene with an arylboronic acid.
