Abstract
This invention relates to a process for preparing 3(4),8(9)-bis(aminomethyl)tricyclo[5.2.1.0.sup.2,6 ]decane. The starting material for the synthesis of this compound is dicyclopentadiene, which is hydroformylated in the presence of a rhodium compound and subjected to reductive amination without the hydroformylation catalyst being separated from the reaction mixture.
Claims31
A process for the preparation of TCD-diamine comprising hydroformylation of dicyclopentadiene in the presence of at least one rhodium catalyst to form a hydroformylation product containing TCD-dial and, without removal of said rhodium catalyst, reaction of said TCD-dial in said hydroformylation product with hydrogen and ammonia in the presence of a hydrogenation catalyst (reductive amination) to form a reaction product containing said TCD-diamine.
