Disubstituted (cyclohexadienyl)iron(1+) complex 2b is prepared by an improved route that starts from 1,2-dimethoxycyclohexa-1,4-diene 3. In five steps, the synthesis of 2b is achieved by complexation with Fe(CO)5, hydride abstraction, hydrolysis, add

Electrophilic tricarbonyl[(1,2,3,4,5-η)-cyclohexadienyl]iron(1+) salts that incorporate methoxy and 2-ethanoyl ester substituents have been prepared, and the regiochemistry of their reactions with nucleophiles in arylation reactions has been examine

A series of aryl-substituted cyclohexadienyliron complexes have been prepared by a general procedure that determines regioselectivity by correctly positioning leaving groups in the precursor complexes. The aryl groups at 1-C or 2-C have been shown to

The coupling of diarylzinc and cuprate reagents with tricarbonyl (2-methoxycyclohexadienylium)iron hexafluorophosphate has been examined in studies which indicate that the efficiency of the coupling step is crucially dependant on the substitution pat

A 1,2-dimethoxy-substituted tricarbonyl(η 5 -cyclohexadienyl(iron(1 +) cation was alkylated predominantly at C(1) to afford an adduct which was converted into a 1-carbomethoxymethyl-2-methoxy-substituted dienyl complex in the first regiocontrolled r

Tricarbonyl(η5-2-methyl-3-methoxycyclohexadienyl)iron(1 +) PF6(1 −) (2) undergoes regioselective alkylation by (−)-1-phenylethylamine and by phosphoramide derivatives of carboxylic acid esters. The diastereomeric 1-phenylethylamine adducts were

This paper reports our experience with the successful simultaneous transplantation of kidney and fetal pancreatic islets in 46-year-old diabetic man. No detectable C-peptide level was noted and the end-stage nephropathy required hemodialysis. The cad
