    • In an ACE-pressure tube under an argon atmosphere the Shvo catalyst (0.02 mmol) and the corresponding alkyl amine (2 mmol of alkyl groups) were dissolved in tert-amyl alcohol (0.5 ml) and aniline (4 mmol). The pressure tube was fitted with a Teflon cap and heated at 150°C for 24 h. The solvent was removed in vacuo, and the crude alkyl aryl amine product was easily purified by column chromatography with pentane-ethyl acetate (20: 1) For an excellent review of the hydrogen borrowing methodology, see:
