Of Aldehyde Or Ketone Containing Compound Patents (Class 564/446)
  • Production of amines
    Patent number: 4292242
    Abstract: Aminomethylation of olefins which employs a homogeneous catalyst which is a solution in a suitable solvent of mixed ruthenium and iron carbonyls. The overall reaction may be represented as follows: ##STR1## where R.sub.1 and R.sub.2 are hydrogen or essentially hydrocarbon groups. The reaction proceeds by way of an aldehyde intermediate. Accordingly, the starting material may be an aldehyde instead of an olefin.

  • Process for the preparation of cyclopropylmethyl-n-propylamine
    Patent number: 4275238
    Abstract: Cyclopropylmethyl-N-n-propylamine is prepared by (a) cyclizing 1,4-butanediol by a cobalt-containing catalyst to 2,3-dihydrofuran at a temperature in the range of about 210.degree.-235.degree. C.; (b) thermally isomerizing the 2,3-dihydrofuran to cyclopropanecarboxaldehyde in an open-reactor columm; and (c) reductively alkylating the cyclopropanecarboxaldehyde with n-propylamine and hydrogen in the presence of a platinum catalyst.
