SELECTIVE oxidative conversion of unbranched primary amines into aldehydes or aldehyde derivatives has not previously been achieved. Two approaches to this problem are envisaged : dehydrogenation of amines, and oxidative deamination. Considerable interest has recently been focused on the dehydrogenation of amine ligands in pro- moting amine oxidations by transition nieta1s.l However, dehydrogenation of unbranched primary amines does not terminate at ...
