“…Gratifyingly, the required transformation of aryl triflates to aryl bromides or iodides has been reported, 29 and with minor modifications, we found it perfectly suitable for the transformation of fluorescein, carbo- and silicofluorescein ditriflates, and rhodol triflates to the corresponding halofluorans (Figure 2). The originally employed cationic Ru(II) catalyst [Cp*Ru(MeCN) 3 ]OTf could in many cases be replaced with a less expensive Ru(III) precatalyst 30 [Cp*RuCl 2 ] n . On the contrary, the corresponding Rh(III) complex [Cp*Rh(MeCN) 3 ](SbF 6 ) 2 was found to be completely ineffective (Table S2), and Grushin’s catalyst 31 [Cp*Ru(η 6 -C 10 H 8 )]BF 4 , presumably operating through a nucleophilic substitution in a η 6 -coordinated Ru(II)-arene π-complex, 32 was much less active.…”

Triarylmethane Fluorophores Resistant to Oxidative Photobluing

Spectral stability of small-molecule fluorescent probes is required for correct interpretation and reproducibility of multicolor fluorescence imaging data, in particular under high (de)excitation light intensities of super-resolution imaging or in single-molecule applications. We propose a synthetic approach to a series of spectrally stable rhodamine fluorophores based on sequential Ru- and Cu-catalyzed transformations, evaluate their stability against photobleaching and photoconversion in the context of other fluorophores using chemometric analysis, and demonstrate chemical reactivity of fluorophore photoproducts. The substitution patterns providing the photoconversion-resistant triarylmethane fluorophores have been identified, and the applicability of nonbluing labels in live-cell STED nanoscopy is demonstrated.

“…The solvents and Me 3 SiCl were distilled from appropriate drying agents and stored under dinitrogen. The complexes [Cp*Ru(OMe)] 2 , [26] [(cymene)RuCl 2 ] 2 , [27] [(C 6 H 6 )RuCl 2 ] 2 , [28] [Cp*RhCl 2 ] 2 , [29] [Cp*IrCl 2 ] 2 , [29] [(1,3,5-C 6 H 3 iPr 3 )RuCl 2 ] 2 , [30] and [Cp*Rh(µ-Cl) 3 RuCl(PPh 3 ) 2 ] (2) [2b] were prepared according to literature procedures. An authentic sample of complex 11 was synthesized by mixing equimolar amounts of [(PPh 3 ) 2 ClRu(µ-Cl) 3 Ru(acetone)(PPh 3 ) 2 ] and [(1,3,5-C 6 H 3 iPr 3 )RuCl 2 ] 2 in CH 2 Cl 2 .…”

“…CDCl 3 was degassed by three freeze–pump–thaw cycles and stored over molecular sieves. [(Cp*Ru) 2 B 3 H 8 (CS 2 H)] ( 1 ), [Cp*RuCl 2 ] 2 , and Li[BH 2 S 3 ] were prepared according to literature methods, while phenylacetylene was obtained commercially and used as received. Thin-layer chromatography was performed on 250 mm aluminum supported silica gel TLC plates.…”

Synthesis, Structure, and Bonding of Bimetallic Bridging Borylene and Boryl Complexes

New synthetic route for the synthesis of diruthenium boryl complexes has been established. Thermolysis of an arachno-ruthenaborane, [(Cp*Ru)2B3H8( CS2H)] (1) (Cp* = η 5 -C5Me5) with phenyl acetylene, led to the formation of bridging boryl borylene complex as [(Cp*Ru)2(µ-HBS2CH2-κ 2 B:κ 2 S){µ-B(C6H4)C(CH3)-κ 2 B:κ 2 C}] (2). In parallel to the formation of 2, the reaction also yielded [(Cp*Ru)(μ-H)BH{HC=C(H)Ph}{SC(H)S}] (3a) and [(Cp*Ru)(μ-H)BH( PhC=CH2){SC(H)S}] (3b). To understand the reaction pathways for the formation of 2, we have thermolyzed 1 in toluene that afforded ruthenium bridging bis(boryl) complex, [(Cp*Ru)2(µ-HBS2CH2-κ 2 B:κ 2 S){µ,η 2 :η 2 -SBH}] (4) along with nido-ruthenathiaborane [(Cp*Ru)2(Me)-(S2B2H3)] (5). Nido-5 is structurally and electronically similar with nido-[(Cp + Ru)2( S2C2Ph2)] (Cp + = η 5 -C5Me4Et), which can be generated from the room temperature reaction of [(Cp + Ru)2(μ,η 1 :η 1 -S2)(μ,η 2 :η 2 -S2)] with diphenylacetylene. Thus, nido-5 can be defined as a true mimic of organometallic cluster nido-[(Cp + Ru)2(S2C2Ph2)]. Complex [(Cp*Ru)2(μ,η 1 :η 1 -S2)(μ,η 2 :η 2 -S2)] ( 6) the Cp* analogue of [(Cp + Ru)2(μ,η 1 :η 1 -S2)(μ,η 2 :η 2 -S2)], can be isolated from the reaction of Li[BH2S3] with [Cp*RuCl2]2 along with a diruthenium boryl complex, [(Cp*Ru)2(μ,η 1 :η 1 -S2)(μ-S2BH-κ 1 B:κ 2 S:κ 2 Sʹ)] (7) in which the boryl unit (S2BH) possesses no bulky heterocyclic ligand. Theoretical studies were performed to shed light on the bonding of these borylene and boryl complexes. The theoretical calculations reveal that the stability of these complexes is due to the strong interaction between the borylene and boryl unit with the ruthenium centers.4, 5, 6 and 7.
