 Title    Enzym atische H ydroxylierung von R uthenocen und O sm ocen durch Leber-M ikrosom en Enzymatic Hydroxylation of Ruthenocen and Osmocene  
 Abstract    In buffer solution (pH 7,4) ruthenocene and osmocene are far more stable than ferrocene. The metallocenes ruthenocene and osmocene are metabolized by microsomes of mouse liver in the presence o f NADPH and 0 2. The Ä'if-values are similar for both metallocenes, the rate of metabolism is higher for osmocene that for ruthenocene.

 Title    Über die Reaktionen von ein-und zweikernigen, kationischen ?/ 5 -Cyelopentadienyl-carbonyl-Komplexeii des Eisens, Rutheniums und Osmiums mit flüssigem Ammoniak [1] On the Reactions of Mono-and Dinuclear, Cationic ^-Cyclopentadienyl Carbonyl Complexes of Iron, Ruthenium and Osmium with Liquid Ammonia [1]  
 Abstract    The covalent carbamoyl compounds 7?5.c5H5Ru(CO)(L)(CONH2) (L = CO, MeCN, MeNC, PPh3, PEt3) and ^-CsHsOsfCOMCONI^) are formed by the reactions of the cationic complexes [7?5.C5H5Ru(CO)2(L)]+ (L = CO, MeCN, MeNC, PPh3, PEt3) and [^ 5 -C5H5Os(CO)3]+ with liquid NH3 below 10 °C. In contrast, the reaction of [^ 5 -C5H5Ru(CO)2(r? 2 -C2H4)]PF6 with liquid NH3 yields the quarternary ammonium salt

 Title    Mesitylene Osmium(II) Complexes Containing the Functional Phosphane ^BuP(CH2C 0 2Me)2 and Anionic Species Derived Thereof as Bi-and Tridentate Ligands  
 Abstract    The dichloroosmium(II) compound [(mes)OsCl2(L)] (2) with L = fBuP(CH2C0 2 Me)2 reacts with one or two equivalents of AgPFö to give the mono-or dicationic complexes 3 and 4 containing the phosphanediyldiester as a bi-or tridentate chelating ligand. Complex 4 undergoes, in the presence of water, partial hydrolysis to give the difluorophosphatoosmium(II) derivative 5 in quantitative yield. Treatment of 4 with two equivalents of KOfBu affords by deprotonation at both CH2 groups of L the neutral complex 6, in which one PCHC0 2 Me unit of the dianionic ligand |7BuP(CHC0 2 Me)2]2-forms a five-membered and the other PCHC0 2 Me unit a three-membered ring with the metal. The reaction of 6 with water leads selectively to the formation of the chelate complex 7 containing the phosphanediylbis(carboxylate) [/BuP(CH2C0 2)2]2~ as a tripodal ligand.

Complexes with cyclic carbene ligands (NC) 4 Pt(-C-O —C—C-NH) 2 (5) and (NC)(Hdmg) 2 Co-C-O-C-C-NH (7) are formed from the corresponding isocyanic metal compounds and oxiranes. 5b has been characterized by crystal structure determination. Ring opening of phenyloxirane occurs at the phenyl substituted carbon atom. (NC) 2 M(CNH) 4 (M = Fe, Ru, Os) and oxirane yield mixtures of (NC) 2 M(—CN—C—C—OH) 4 and (NC) 2 M[—CN—C—C—(—O—C—C—)"—O—C—C—OH] 4 .
