Oxidative carbon carbon bond cleavage reaction of 1,2-diamines and 1,2-amino alcohols under an oxygen atmosphere
摘要:
Under an atmosphere of oxygen 1,2-diamines underwent clean oxidative cleavage in the presence of BF3-OEt2 to give imines in good to excellent yields. 1,2-Amino alcohols were also cleaved under the same conditions to give imines and aldehydes in good yields.

Aromatic aldimines are reductively coupled to 1,2-diamines by treatment with samarium diiodide. Cross-coupling of aromatic ketimines with ketones to 2-aminoalcohols is also promoted by the same reagent.
