(2-(Dimethylamino)ethyl)cyclopentadienyl Group VI Metal Carbonyl Anions and Divalent Tin(IV) Derivatives

Abstract

ethyl)cyclopentadienyl (Cp N ) group VI metal carbonyl anions ([M(CO) , important reagents for studies involving Cp N , have been characterized by X-ray crystallography. These anions (M′ ) Mo, W) react with R 3 SnCl (R ) Ph, cyclohexyl) to provide structurally characterized tin(IV) derivatives.

The chemistry of group-VIb metal carbonyls

“…The HL proved to act as a tridentate ligand [188]. Salts of (2-(dimethylamino)ethyl)cyclopentadienyl (Cp N ) group VI metal carbonyl anions ( [M(CO)3(η 5 -Cp N )] -(M = Cr, Mo, W)) were reported (Scheme 46) [189].…”

Reactivity of a trinuclear ruthenium complex involving C–H activation and insertion of alkene

“…10,11 For the pyridyl side-chain-functionalized indenyl ligands, the nitrogen atom can act as a good two-electron donor site and can coordinate to a variety of metals, and intramolecular coordination to a Lewis acidic metal center or construction of oligonuclear metal complexes usually shows different structures and reactivities. [12][13][14][15] In addition, some cyclopentadienyl metal complexes containing a substituted donor-functionalized side chain and a Cp*Ru cluster that C-H activates pyridine have been reported. [16][17][18][19] In our previous work we studied the reactions of pyridyl-substituted cyclopentadienes with Ru 3 (CO) 12 and obtained ruthenium carbonyl complexes involving novel intramolecular C-H activation and normal products.…”
