Title: Substituted benzidine derivatives, process for their manufacture and their application in the therapeutic field
Inventor: URBAIN MICHEL
IPC: A61K31/655
Filed: 1987-03-17
Abstract: The substituted benzidine derivatives according to the present invention are represented by the following general formula: where R1 and R2 represent a hydrogen atom, a methyl radical or a sulphonic acid group. A and B represent derivatives either of 2,8-diamino-1-naphthol-3,5-disulphonic acid or of 1,2-diaminonaphthalene-3,5-disulphonic acid. Derivatives are obtained by prior synthesis of the derivative corresponding to diazotised benzidine, then subsequently condensed with the derivatives A and B in alkaline medium. In the case of halogenated derivatives, the halogenation can be carried out after condensation of naphthalenedisulphonic acid and diazo-ortho-tolidine. In the case of alcoholic and phenolic derivatives, substitution by the alcohol or the phenol is carried out by heating at reflux. These products are used as antiviral agents; they can be used externally or parenterally.

Patent FR-2615123-A1 (FR)
Inventor: FUCHS JEAN-MARC
IPC: C07C2/24
Filed: 1987-05-15
Abstract: The catalyst for the dimerization of propylene into methyl-4-pentene-1 comprises potassium (K) and potassium carbonate (K2CO3) and is characterized in that it further contains at least one metal (M) selected amongst manganese, chromium, cadmium, nickel, palladium and titanium. It may also include copper. The method for preparing the catalyst comprises the following steps carried out in the presence of an inert liquid having a high boiling point. In a first step, a suspension of potassium carbonate is obtained in the inert liquid. In a second step, the metal or metals (M), and optionally copper, are introduced in powder form into the highly stirred reaction medium. In a third step, after bringing the reaction medium to a temperature higher than the potassium melting temperature, potassium is introduced under high stirring conditions. In the fourth step, the reaction medium is brought to a temperature comprised between 140 and 180 DEG C during a length of time comprised between 1 and 3 hours, and the reaction medium is then allowed to cool down to room temperature. The process for dimerization of propylene into methyl-4-pentene-1 uses the catalyst disclosed hereabove.
