标题:Material based on tungsten carbide(s), catalyst and process useful for the hydrogenation of an aromatic nitro or nitroso derivative employing this catalyst
发明人：JACQUOT ROLAND; MERCIER CLAUDE
权利人:RHONE POULENC CHIMIE
摘要:The present invention relates to a process and a catalyst for hydrogenation of aromatic nitro or nitroso (nitrosated) compounds. The process, useful in hydrogenation, especially in the liquid phase, of compounds, nitroaromatic ones in particular, is defined in that the said compound is hydrogenated in the presence of tungsten carbide, the partial pressure of hydrogen being at least equal to two atmospheres (2x105 pascals). The process also has application to organic synthesis.

摘要:The present invention describes new pyrazolo-pyrimidine derivatives which are generally interacting with MALT1 proteolytic and/or autoproteolytic activity, and in particular which may inhibit said activity. The present invention further describes the synthesis of said new pyrazolo-pyrimidine derivatives, their use as a medicament, especially by interacting with MALT1 proteolytic and/or autoproteolytic activity.
