A simple synthesis of trans-RuCl(CCR)(dppe)2 complexes and representative molecular structures

Functionalization of a Ruthenium–Diacetylide Organometallic Complex as a Next‐Generation Push–Pull Chromophore

“…The first step consists of the formation of a vinylidene moiety, [ 3 ][TfO], featuring the electron‐donor part of the target push–pull complex. Stable ruthenium vinylidene complexes are easily obtained by treating the 16‐electron species [(dppe) 2 RuCl][TfO] ([ 1 ][TfO]) with the appropriate alkyne,23 in this case N ‐(4‐ethynylphenyl)carbazole ( 2 ). The subsequent reaction of [ 3 ][TfO] with 4‐ethynylbenzaldehyde, in the presence of the noncoordinating NaPF 6 salt and Et 3 N as a base, led to the formation of the bis(σ‐arylacetylide) intermediate complex 4 .…”

“…All reagents were obtained from commercially available sources and used without further purification, otherwise stated. [(dppe) 2 RuCl][[TfO] ([ 1 ][TfO])23 and 4‐ethynylbenzaldehyde30 were prepared as previously reported.…”

HN2O2− as a Ligand in Mononuclear Hydrogenhyponitrite‐κ2‐N,O Ruthenium Complexes with Bisphosphane Co‐Ligands

“…In comparison to known literature on complexes with cis dppe chelates, this synthesis had fewer steps and the product was obtained in quantitative yield. [24] In addition, [Ru(dppv) 2 (H 2 O) 2 ](BF 4 ) 2 (3)w as used as as tarting materiala nd synthesized according to the methods used for 1 and 2.T he octahedral complex consists of two apical 1,2-bis(diphenylphosphino)ethene (dppv) bisphosphane ligandsa nd two axial aqua ligands coordinated to the ruthenium(II) center ( Figure 3).…”

Synthesis and characterization of new mono and bi-nuclear ferrocene derivatives connected via a cross-conjugated prop-2-en-1-one bridge

“…Ferrocenecarboxaldehyde, acetylferrocene, ethynyltrimethylsilane, 4'-bromoacetophenone, 4-bromobenzaldehyde and 1-iodo-4-nitrobenzene were purchased from Aldrich and used without further purification. The synthesis of 3-ferrocenyl-1-(4'-bromophenyl), A, 4-ethynylacetophenone, C, 4-ethynylbenzaldehyde, D, and [RuCl(dppe) 2 ]OTf were previously reported [41,58,59]. The already reported compound 1-ferrocenyl-3-(4'-bromophenyl)-prop-2-en-1-one [53], B, was obtained by the following modified method: 246 mg of KOH (4.38 mmol), was dissolved in 40 mL of methanol and 10 mL of water.…”
