On the structure and properties of 2-copper-1-(dimethylaminomethyl)ferrocene

Abstract Some properties of 2-copper-1-(dimethylaminomethyl)ferrocene [1] have been studied (thermal decomposition, decomposition by strong (HCl) and the crystal structure of this organocopper compound has been determined.

Reaction of boric acids of ferrocene with copper tetraphenylborate

The reaction of copper tetraphenylborate with 1-(1′-bromoferrocenyl)boric acid and ferrocenylboric acid results in the respective formation of phenylferrocene (together with a small amount of 1,1′-diphenyl-ferrocene) and ferrocene (together with phenylferrocene and biferrocenyl).

Properties of α-ferrocenylcarbonium ions

1. Phenylferrocenylcarbonium and diphenylferrocenylcarbonium tetraphenylborates alky late dimethylaniline in the p-position with the respective formation of p-dimethylaminodiphenylferrocenylmeuiane and p-dimethylaminotriphenylferrocenylmethane, 2. The preparation of p-dimethylaminophenylferrocenyl-, p-dimethylaminodiphenylferrocenyl- and p-dimethylaminophenyldiferrocenylcarbinols was described.

Photolysis of 1,1′-ferrocenedicarboxylic acid

1,1′-Ferrocenedicarboxylic acid undergoes decomposition under the influence of light with a rupture of the C-Fe bond and the formation of the dimer of cyclopentadienecarboxylic acid.

Intermolecular hydrogen bonding in β-hydroxycarbonyl ferrocene compounds

Conclusions1.IR and PMR spectroscopy was used to study the different types of hydrogen bonds formed in solutions of β-hydrocarbonyl ferrocene compounds. The observed spectral behavior can be explained by the formation on an intramolecular hydrogen bond of the OH group with the iron atom only in the case of a dilute solution of the ethyl ester of 3-hydroy-2-(phenylferrocenylmethyl)-3-methylbutanoic acid.2.Only OH⋯OH− and OH⋯O=C interactions were found for this isomer in the crystalline state.

Unsaturated ketones in cymantrene and ferrocene series

ConclusionsSome unsaturated ketones with ferrocenyl and cymantrenyl groups are described, and the IR, PMR, and UV spectral data are given.

The synthesis of ferrocenylboric and 1,1′-ferrocenylenediboric acids

Detailed methods for preparing ferrocenylboric and 1,1′-ferrocenyleneboric acids in relation to the conditions for metallizing the ferrocene are presented.

Reactions of organomagnesium compounds with potassium and triethyloxonium fluoborates

1. A study has been made of the reaction of potassium fluoborate with orgnaomagnesium compounds, namely phenylmagnesium, p-tolylmagnesium and p-methoxyphenylmagnesium bromides and methylmagnesium iodide. In the first two cases, the products were potassium tetraphenylboron and potassium tetra-p-tolyboron, respectively. where as p-methoxyphenylmagnesium bromide and methylmagnesium iodide yielded tris-p-methoxyphenylborine, and triphenylborine, respectively. 2. By reaction in pyridine of the copper derivative of acetoacetic ester with potassium tetraphenylboron and with potassium tetra-p-tolyboron the pyridinates of cuprous tetraphenylboron and cuprous tetra-p-tolylboron were obtained. 3. By reaction with phenylmagnesium bromide, and also with potassium tetraphenylboron, triethyloxonium fluoborate yields triethyloxonium tetraphenylboron.

4-Benzalpyrazolines with metallocenyl substituents

Conclusions4-Benzal derivatives of pyrazolines that contain metallocenyl substituents in the 3 and 5 positions are described.

Some reactions of organosilver compounds of chloroferrocene

Conclusions1.The reaction of 1-(1′-chloroferrocenyl)silver and 1-(2-chloroferrocenyl)silver with iodine gives, respectively, 1′-chloro-1-iodoferrocene and 1-chloro-2-iodoferrocene, and the corresponding dichlorodiferrocenyls.2.The reaction of the organosilver compounds of chloroferrocene with iodobenzene gave, respectively, 1′-chloro-1-phenylferrocene and 1-chloro-2-phenylferrocene, which were reacted with copper phthalimide and copper acetate.
