Usage

General Description

CARBONYLBROMOBIS(TRIPHENYLPHOSPHINE)RHODIUM(I) is a chemical compound that consists of a rhodium atom coordinated to two triphenylphosphine ligands and a carbonyl ligand, as well as a bromine atom. This complex is commonly used as a catalyst in organic synthesis, particularly in the formation of carbon-carbon bonds through various reactions such as hydrogenation, hydroformylation, and carbonylation. The presence of the triphenylphosphine ligands and carbonyl ligand allow the rhodium center to facilitate these transformations by stabilizing key intermediates and facilitating the transfer of ligands during the reaction process. The compound is also known for its high reactivity and ability to activate small molecules, making it a versatile and valuable tool in the field of organometallic chemistry.

Novel Halogen Exchange Reactions between Halosilanes and Rh(I) or Ir(I) Complexes

Vaska-type complexes such as MCl(CO)L2 (M=Rh or Ir, L= tertiary phosphine) or the Wilkinson complex RhCl(PPh3)3 underwent halogen exchange reactions with halosilanes Me3SiX (X=Br, I) to give MX(CO)L2 or RhX(PPh3)3 respectively with the formation of Me3SiC

THE PREPARATION OF cis- AND trans- (Ar = ARYL) AND THEIR READY DISSOCIATION IN SOLUTION

Attempts to prepare complexes have shown that when X=I these complexes are far less stable than the well-known .The bromo complexes (Ar=C6H5, p-EtC6H4) can be prepared by simple halide exchange from their respective chloro complexes.However a similar attempt to prepare the iodo complexes was frustrated by dissociative equilibria; in the absence of oxygen dimers were formed, whereas in the presence of oxygen polymeric oxygen complexes were formed.The ease of dissociation of phosphine can be attributed to the greater steric crowding in the iodo complexes than in the chloro and bromo complexes.The complex could only be obtained in the presence of excess PPh3, which inhibits the dissociation.The identification of this monomer was further complicated by the previously unnoticed presence of both cis and trans isomers in the solid state.

REACTIONS INVOLVING TRANSITION METALS. XII. SOME ATTEMPTS TO PREPARE ALKYLIDYNETRIRHODIUM CLUSTER COMPOUNDS

Attempts to prepare alkylidyne-trirhodium cluster complexes by reaction of Na with CX4, CHX3 (X = Cl or Br) and CCl3CF3 have resulted only in the formation of .With CHCl3 at -20 deg C the major product is 2, though to be formed by decomposition of .Reaction between Na and perfluoroacyl chlorides has given the new compounds F)(CO)2(PPh3)2> (RF = CF3, C2F5 and C3F7), which do not decarbonylate even after 6-9 days at 120 deg C.Tetrafluoroethylene has been found to react with under UV irradiation conditions to give in 33percent yield.The latter does not react with to form clusters, but surprisingly, its reaction with Na resulted in a low yield of CF3CCo3(CO)9; under similar conditions Na caused only decomposition.
