Title: Process for the production of new pyridine derivatives
IPC: C07D471/04
Filed: 1926-10-14
Abstract: 259,982. Deutsche Gold-und Silber- Scheideanstalt vorm. Roessler. Oct. 17, 1925, [Convention date]. Pyridine derivatives are obtained by condensing 3-hydrazinopyridine, or derivatives of 2- or 3- hydrazinopyridine, with aliphatic, aromatic or aliphatic-aromatic aldehydes or ketones. A solvent may be present and a condensing agent may be used. Examples are given of the interaction at ordinary temperature of 3-pyridylhydrazine (prepared by reducing diazotized 3-aminopyridine with stannous chloride) with benzaldehyde, 2- chloro-5-hydrazinopyridine with acetoacetic ethyl ester, and 2-hydrazino-5-nitropyridine with acetoacetic ethyl ester, acetone, propionic aldehyde or benzaldehyde. By the use of higher temperatures, preferably above 100‹ C., the condensation between the hydrazinopyridine and an acetoacetic ester may be carried further: for example, by heating 2-hydrazino-5-nitropyridine with acetoacetic ethyl ester or by heating their initial condensation product, 1-(5-nitro-2-pyridyl)-3-methyl- 5-pyrazolone is produced. Again, the condensation products, except those from acetoacetic esters, may be heated with agents capable of splitting off ammonia, such as zinc chloride or alcoholic hydrochloric acid: thus. 2-methyl-5- chlorpyrindol results from this treatment of the condensation product of 2-chlor-5-hydrazinopyridine and acetone. and 3-methyl-5-chlorpyrindol from this treatment of the condensation product of 2-chloro-5-hydrazino pyridine and propionic aldehyde. Specifications 255,811 and 259,961 are referred to. Derivatives of 2-hydrazinopyridine are prepared by treating the corresponding derivatives of 2- halogenpyridine with hydrazine hydrate. An example is given of the preparation of 2- hydrazino-5-iodopyridine from 2-chloro-5-iodopyridine.

Title: Improvements in and relating to the production of organo-aluminium halide compositions
Inventor: SMITH PETER
IPC: C07F5/06
Filed: 1958-08-11
Abstract: An alkyl aluminium sesquihalide is converted into an alkyl aluminium halide composition having a ratio of alkyl groups to halogen atoms greater than that in the sesquihalide by first reacting it with an alkali metal to give a reaction product containing metallic aluminium and then treating this reaction product with sufficient primary alkyl halide to react with the metallic aluminium.  The final product consists essentially of a dialkyl aluminium monohalide mixed with an alkyl aluminium dihalide or with a trialkyl aluminium.  It is preferred that the sesquihalide should be a sesquichloride and that the alkyl group is methyl or ethyl.  The process may be carried out in an inert solvent such as a paraffinic or saturated alicyclic hydrocarbon, at a temperature between 0 DEG C. and 200 DEG C. and at atmospheric or moderately elevated pressure.
