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

Five-coordinate dicarbonyl complexes of rhodium(I): (X = Cl, Br, I)

The complexes trans- (1, X = Cl, Br, I) react with CO to form (2), and not to form cis-.Complexes 2 contain equivalent axial carbonyl ligands.It is proposed that a series of dicarbonyl complexes, including 2, is formed during decarbonylation reactions catalyzed by 1.

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. XVII. REACTION OF ORGANIC HALOGEN COMPOUNDS WITH 2 AND 2 (S = CH2Cl2, THF)

The complexes 2 and 2 (S=CH2Cl2, THF) have been shown to react with CXCl3 (X=Cl, H) to form with generation of both dichlorocarbene and trichloromethyl radical.Reaction of 2 with CF3I, allyl- and benzyl-halides takes a different course giving organic coupling products and .The THF solvate complex also causes coupling of gem-dihalides, and dehalogenation of vic-dihalides to produce alkenes.Possible mechanisms for these reactions are discussed.

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.
