Carbon–sulphur and carbon–hydrogen bond cleavages in the reactions of phenyl vinyl sulphide with triosmium clusters: crystal structure determination of [Os3(µ-SPh)(µ-CHCH2)(CO)10]
Autor: Esther B. Boyar, Mary McPartlin, Kim Henrick, Antony J. Deeming, Anthony Scott
Publikováno v: J. Chem. Soc., Dalton Trans.. :1431-1435
Phenyl vinyl sulphide inserts at room temperature into an Os–H bond of [Os3H2(CO)10] to give two diastereomers of the cluster [Os3H (µ-PhSCHMe)(CO)10]. However, under similar conditions the sulphide oxidatively adds to [Os3(CO)10(MeCN)2] with C–

Chelation of vinyl acetate and related unsaturated ketones: molecular structure of [Os3(CO)10(CH2CHOCOMe)]
Autor: Mary McPartlin, Antony J. Deeming, Kim Henrick, Esther B. Boyar, Ian P. Rothwell
Publikováno v: J. Chem. Soc., Dalton Trans.. :1437-1441
The cluster [Os3H2(CO)10] reacts with neat vinyl acetate at room temperature to give complexes [Os3H (CHCH2)(CO)10](5%) and [Os3(CO)10(CH2CHOCOMe)](1)(43%). Complex (1) has also been obtained (30%) from [Os3(CO)10(MeCN)2]. The X-ray crystal structure

Publikováno v: J. Chem. Soc., Dalton Trans.. :5-12
The µ3-ethynyl compound [Os3H(CCH)(CO)9] reacts smoothly with ethanol as the solvent to give two isomeric ethanol adducts: [Os3H2(CCHOEt)(CO)9](1) and [Os3H2(CHCOEt)(CO)9](2), derived by ethoxy-group addition at the β- and α-carbon atoms respectiv

Triosmium clusters containing ligands derived from tropone (cycloheptatrienone): molecular structure of an oxidative addition product [Os3H(µ3-C7H5O)(CO)9]
Autor: Paul A. Bates, Michael B. Hursthouse, Neil P. Randle, Esther B. Boyar, Antony J. Deeming
Publikováno v: J. Chem. Soc., Dalton Trans.. :551-555
Tropone (cycloheptatrienone, C7H6O) reacts in refluxing cyclohexane with [Os3H2(CO)10] to give the oxidative addition product [Os3H(C7H5O)(CO)10](1), also formed from [Os3(CO)10(MeCN)2], and the insertion product [Os3H(C7H7O)(CO)10](2). Structures ba
