Alkyne Activation by Electrophilic [(.eta.-C5Me5)Ru(NO)(R)]+ (R = Me, Ph, p-tolyl) Fragments: .beta.-Migratory Insertion, Isomerization, and Metallacycle Formation

(Glycol-κ2O,O′)nitrosyl(η5-pentamethylcyclopentadienyl)ruthenium(II) bis(trifluoromethanesulfonate)

“…Data collection: APEX2 (Bruker, 2004); cell refinement: APEX2; data reduction: SAINT (Bruker, 2004); program(s) used to solve structure: SHELXS97 (Sheldrick, 1997); program(s) used to refine structure: SHELXL97 (Sheldrick, 1997); molecular graphics: SHELXTL (Sheldrick, 2000); software used to prepare material for publication: publCIF (Westrip, 2008 (Svetlanova-Larsen et al, 1996), unsaturated hydrocarbons (Burns & Hubbard, 1994), and alcohols, and results in their binding and activation. For primary and secondary alcohols, after initial coordination, the reaction leads to alcohol oxidation and reduction of the ruthenium center to the Ru=Ru dimer, (Pearsal et al, 2007).In the case of ethylene glycol, however, the coordination product is stabilized by a chelate ring formation and can be isolated and characterized.…”

Organometallic Ruthenium Nitrosyl Obtained by C–H Bond Activation – Photoinduced Delivery of Nitric Oxide and NO‐Mediated Antiproliferation Activity Studies

“…[6a], [6b] The NO stretching frequencies (ν NO , ν̃ ≈ 1820 cm –1 , vide infra) and N–O bond length are also consistent with previously reported values ,. [6b] The Ru–N and N–O bond lengths as well as the Ru–N–O angle[6a], , (ca. 172° for 1a· CH 2 Cl 2 ) revealed the π ‐acceptor characteristics of the coordinated NO + ligand in the complex and demonstrated the {Ru II –NO + } 6 description of the {RuNO} 6 moiety ( S = 0 ground state).…”
