Organometallic Compounds. XVI. Synthesis of trans-1, 2-Diferrocenoylethylene

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Synthesis of Sulphones from Sulphonyl Fluorides and Organometallic Compounds

Introduction Recently, /3-disulphones wrere synthesised in high yields from sulphonyl fluorides by interaction with alkylmagnesium bromides [1]. It is assumed that this reaction proceeds through the formation of a monosulphone which undergoes a-metallation followed by further reaction with the sulphonyl fluoride to produce /?-disulphone. Since aromatic sulphones cannot be metallated at the a-po...

Synthesis and characterization of organometallic Schiff base compounds

Synthesis of trans-2-(1-aryl-1-methylethyl)cyclohexylamines.

As a first example of opening a secondary aziridine with a tertiary carbanion, the title amines (3a-c, aryl = phenyl, 4-tert-butylphenyl,2-naphthyl) were synthesized by opening N-(diphenylphosphinoyl)-7-azabicyclo[4.1.0]heptane, aziridine 1, with the corresponding alpha-potassium isopropylarenes, followed by a hydrolysis of the resulting phosphinamides 2a-c.
