Rhodium complexes with thallium

Lithium or potassium indenyl has been used to generate both iridium complexes and isocyanide rhodium complexes of the form (n indenyl)Rh(CNR)2. Bimetallic complexes of Co,Rh and Ir have been made using thallium fulvanate Tl2(CioH8)- With the linked permethylcyclopentadienyl lithium reagent dirhodium complexes such as (19) can be made. ... 

The osmiamate in is the source of most other osmium nitrido complexes. The free acid is said to be 0sN(0H)02 in the solid state and the Bu"4N, Ph4P+, Pli4As+, lithium, rhodium, potassium, rubidium, cesium, ammonium, silver, thallium, mercury, zinc, barium and lead salts are also known. The preparation of the potassium salt of OSO4 in concentrated KOH solution with NH4OH is a simple method for obtaining this useful starting material. ...

The compound Rh(acac)(coe)2 is long known, but a new synthetic protocol from [Rhl/t-ClXcoelzlz with Na(acac) (without the use of a thallium salt) was reported and the crystal structure of the compound was determined by X-ray diffraction studies. The thermal reaction of Rh(acac)(CO)2 with alkenes was studied and a series of rhodium alkene complexes, Rh(acac)(CO)(alkene) (alkene = ethylene, 1-propene, 1-octene), were characterized. The catalytic... 

The rhodium (triphenylphosphine)(ethene) complex CpRh(PPh3)(C2H4) 349, was synthesized by the reaction of [RhCl(G2H4)2]2 with triphenylphosphine and thallium cyclopentadienide. As in CpRh(PMe3)(C2H4), the coordinated ethene ligand may be displaced photochemically, affording a series of oxidative addition reactions.Complexes of the type Cp Rh(olefin)2 are found to be excellent catalysts for the isomerization of aldehydes or transfer formylation reactions." Divinyl disiloxane or divinyl disilazane afforded the preparation of several complexes of Rh-Cp, such as 350, 351, and 352. ...
