Abstract:

Abstract The 2.5-difurfurylpyrrole-O.N.O ligands 3a, b [R = CO2C2H5 (a). COCH, (b)] are obtained by reaction of the furanes l a , b with the 2,5-bis(chloromethyl)pyrrole 2 in the presence of SnCl4. Proton abstraction from 3a, b with NaH affords the sodium salts 4a-Na and 4b-Na. Exchange of the chlorine bridges in [μ-ClRh(Diol)]2 (5,5') (Diol = cyclooctadiene, norbornadiene) results in the formation of the 14-electron complexes (Diol)Rh(O.N.O) (6a,6'a). Addition of PPh3, yields the four-coordinated rhodium complexes (Diol)Rh(O.N.O)(PPh3) (7a,7'a). These compounds are also available in a reverse

Abstract:

Chiral bis-imidazole rhodium(III) complexes catalyze the allylation of aldehydes by allyltributyltin. The pre-catalyst was readily prepared from chiral N,N'-bis(N-methyl-2-methylene-4,5-bisphenylimidazole)-1,2-cyclohexanediamine, potassium carbonate, and rhodium(III) chloride trihydrate. The rhodium(III) complex produced showed no activity in an allyl transfer process in the presence of the allyltin reagent. However, when silver tetrafluoroborate was added to the pre-catalyst and stirred for 1 h, the resulting system became an efficient catalyst for the allyl transfer process. The reductions p

Abstract:

Cyclic and bicyclic sulfates have been prepared from commonly available alcohols. Nucleophilic cleavage of the cyclic sulfates affords a new type of water-soluble mono- and ditertiary phophines bearing -OSO3Li groups in distinguished positions in the molecular framework. Both phosphines have amphiphilic character. Reactions of the chiral 2 and the dppp analogue 5 with [Rh(COD)Cl]2 and Pt(PhCN)2Cl2 provide novel zwitterionic complexes. Rhodium complexes of 2 and 5 have been successfully applied in liquid biphasic hydroformylation of styrene and octene-1. When the rhodium complex of 5 was used a

Abstract:

A PAlP pincer ligand derived from 2-diphenylphosphino-6-isopropylphenol was synthesized. The Lewis acidity of the Al center of the ligand was evaluated with coordination of (O)PEt3. A zwitterionic rhodium-aluminum heterobimetallic complex bearing the PAlP ligand was synthesized through its complexation with [RhCl(nbd)]2. Moreover, reduction of the zwitterionic rhodium-aluminum complex with KC8 afforded heterobimetallic complexes bearing an X-type PAlP pincer ligand.

Abstract:

Reactions of ruthenium(III) chloride and rhodium(III) halides with 1,2-bis(N-methylbenzimidazolyl)benzene (N-N) in stoicheiometric amounts in methanol produced binuclear complexes of the compositions [RuCl2(- Cl) (N-N)]2 and [RhX3(N-N)]2. nH2O ( n = 0, X = Br ; n = 1, X = Cl). [RhI3(N-N)]2 was prepared by stirring a mixture of rhodium trichloride with fifteen fold excess of sodium iodide and the N-heterocycle, N-N in methanol. Ruthenium chloride and rhodium halides in 2-methoxyethanol/alcohol reacted with N-N in presence of CO to produce complexes of the types [RuCl2(CO)2(N-N)], [Rh2Cl2(CO)2(

Abstract:

The coordination versatility of a 1,3,5-triphenylbenzene-tris-mesoionic carbene ligand is illustrated by the preparation of complexes with three different metals: rhodium, iridium and nickel. The rhodium and iridium complexes contained the [MCl(COD)] fragments, while the nickel compound contained [NiCpCl]. The preparation of the tris-MIC (MIC = mesoionic carbene) complex with three [IrCl(CO)2] fragments, allowed the estimation of the Tolman electronic parameter (TEP) for the ligand, which was compared with the TEP value for a related 1,3,5-triphenylbenzene-tris-NHC ligand.

Abstract:

The novel metal complex ions pentaammine ( trimethyl phosphate)- rhodium(III) and -iridium(III) have been synthesized and their hydrolysis in basic solution studied. The hydrolyses yield coordinated dimethyl phosphate ( dmp ), exclusively for the iridium complex, but accompanied by metal-oxygen bond rupture in the case of the rhodium complex. The reaction of the iridium complex proceeds with phosphorus-oxygen cleavage. The hydrolyses in the absence of nucleophiles other than hydroxide obey simple rate laws, v = k1[(NH3)5Ir( tmp )][OH-] for the iridium complex and v = (k1 + k2[OH-])[(NH3)5Rh( t
