this is it...for those who have access to Pd/C, formic acid and the amines of choice, the method above is the way to go when reductively aminating carbonyls to make secondary or tertiary amines. check the table below! oh how nice is it that anhydrous conditions disfavor high yields :)

combine this with Synth. Commun. 20, 2453 (1990), and you have another high yielding route to ketones (after acid hydrolysis of the oximes made by this CTH with formates) as your precursors to employ in the other route mentioned above.

US2007078282 holds some information on how catalytic hydrogenation can be modified with TiO2, ZrO2...anybody think this can also favorably be employed in CTH using formates?
