A. Goti et M. Romani, CATALYTIC-OXIDATION OF SECONDARY-AMINES WITH TETRA-N-PROPYLAMMONIUM PERRUTHENATE, Tetrahedron letters, 35(35), 1994, pp. 6567-6570
Oxidation of secondary amines by N-methylmorpholine N-oxide and cataly
tic amounts of tetra-n-propylammonium perruthenate (TPAP) affords stra
ightforwardly the corresponding imines in good yields.
