Bis(acetylido) Complexes of Ruthenium(II) Bearing Monodentate Phosphane Ligands

“…[35] cis-RuMe 2 (dmpe) 2 was prepared according to a literature procedure. [36] cis/trans-Ru(CϵCPh) 2 (PMe 3 ) 4 (2): Phenylacetylene (0.40 mL, 3.64 mmol) was added to a solution of cis-RuMe 2 (PMe 3 ) 4 (1, 0.148 g, 0.340 mmol) in thf (10 mL). The mixture was warmed to 40°C for 2 h, after which time the volatiles were removed in vacuo.…”

Nucleophilic attack on η3-allyl and η2-tetrahydroborate complexes of ruthenium(ii)

“…Thus 16 was [Ru(η 1 -BH 4 )(CO)-(η 2 -C 2 H 4 )H(PMe 2 Ph) 2 ], the ethene equivalent of 11, 12, and 13, although not necessarily with the same ligand arrangement (see below). Ruthenium complexes containing both a hydride and an ethene ligand appear to be rare: a recent report 28 gave only one example of an octahedral ruthenium() complex of this type, [Ru(η 2 -C 2 H 4 )H(Me 2 PCH 2 CH 2 PMe 2 ) 2 ] ϩ : 29 in this complex the ethene and hydride ligands are mutually trans. Such a ligand arrangement would match those for 11, 12 and 13.…”

Insertion of CO2 into the Ru−C Bonds of cis- and trans-Ru(dmpe)2Me2 (dmpe = Me2PCH2CH2PMe2)

“…Reaction of cis-Ru(dmpe) 2 Me 2 (1) and trans-Ru(dmpe) 2 -Me 2 (2) with CO 2 . cis-Ru(dmpe) 2 Me 2 (1) was synthesized by the reaction of Ru 2 (OCOCH 3 ) 4 Cl with Mg(Me) 2 , 29 and trans-Ru(dmpe) 2 Me 2 (2) was synthesized from the reaction of trans-Ru(dmpe) 2 Cl 2 with MeLi according to literature procedures. 30 The cis and trans isomers can be synthesized in pure form; however the trans isomer can be readily isomerized to the more thermodynamically stable cis isomer, and the isomerization properties have previously been reported.…”

“…cis -Ru(dmpe) 2 Me 2 ( 1 ) and trans -Ru(dmpe) 2 Me 2 ( 2 ) were prepared following literature methods. , Ru(dmpe) 2 H 2 and Ru(dmpe) 2 HCl were prepared using a modified literature preparation. , …”
