Abstract: In a process for preparing aminopropyl alkoxy silanes comprising reacting an allylamine with a hydro-alkoxy silane in the presence of a rhodium catalyst, the improvement which comprises use of a rhodium phosphide or its oligomer as said rhodium catalyst. By this process the desired gamma-isomer can be prepared in a high selectivity and yield within a short reaction time.

Abstract: A process for preparing aminopropyl alkoxy silanes comprising reacting an allylamine having at least one active hydrogen atom attached to the amine nitrogen atom with a hydro-alkoxy silane having from 1 to 3 alkoxy groups attached to the silicon atom in the presence of a rhodium complex having inorganic ligands, at least one of said ligands being carbonyl. By this process the desired gamma-isomer can be prepared in a high selectivity and yield within a short reaction time. When the reaction is carried out in the presence of carbon monoxide and/or a cyclic olefinic compound, the selectivity and yield of the gamma-isomer can be further improved. The presence of carbon monooxide in the reaction system further serves to lengthen the catalyst life and to reduce the amount of the catalyst to be used.

Abstract: In an oxo process wherein an olefin is caused to react with carbon monoxide and hydrogen, a rhodium catalyst is provided by carrying out the hydroformylation in the presence of a rhodium source and free mixed ligands comprising a tertiary organo phosphorus and tertiary organo arsenic in excess of the quantity required for coordination to the rhodium atom. For example, HRh(CO)(PPh.sub.3).sub.3 with excess AsPh.sub.3 /PPh.sub.3 may be used to give a high reaction rate and good selectivity to n-aldehyde.
