Carbenerhodium(I) complexes of the half-sandwich-type: reactions with electrophiles
Autor: Peter Dr. Schwab, Helmut Werner, Matthias Laubender, Elke Bleuel
Publikováno v: Journal of the Chemical Society, Dalton Transactions. :266-273
The reaction of the carbenerhodium(I) complexes [(η5-C5H5)Rh(CR2)(L)] (R = aryl) with HX (X = Cl, CF3CO2) led, depending on the size and donor properties of the ligand L, to two different types of products. While compounds 1, 2 with R = Ph and L = C

Diphenylcarbene rhodium complexes: of the halfsandwich type with (η5-C5H4SiMe3)Rh as a molecular unit
Autor: Helmut Werner, Elke Bleuel
Publikováno v: Comptes Rendus de l'Académie des Sciences - Series IIC - Chemistry. 2:341-349
The square-planar rhodium(I) complexes trans -[RhCl(=CPh 2 )(L) 2 ] (L = Sb i Pr 3 , P i Pr 3 , PPh 3 ) react with LiC 5 H 4 SiMe 3 to give the halfsandwich type compounds [(η 5 -C 5 H 4 SiMe 3 )Rh(=CPh 2 )(L)] 7–9 in good to excellent yields. Whi

The First Example of Linkage-Isomeric Ketene Metal Complexes
Autor: Matthias Laubender, Elke Bleuel, Helmut Werner, Birgit Weberndörfer
Publikováno v: Angewandte Chemie International Edition. 38:156-159
With [(C9H7)Rh(PiPr3)] as molecular unit and diphenylketene as ligand, it has been possible for the first time to isolate linkage-isomeric ketene metal complexes (1 and 2). With regard to the hard/soft acid/base (HSAB) concept, it is surprising that

Publikováno v: Organometallics. 17:10-12
Reaction of [(η5-C5H5)Rh(CPh2)(PiPr3)] (2) with either PF3 or HX (X = Cl, CF3CO2) leads to a migratory insertion of the carbene ligand into one of the C−H bonds of the cyclopentadienyl ring. The X-ray crystal structures of [(η5-C5H4CHPh2)Rh(PF3)(
