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.

This paper describes a unique application of the fluoronium cation (F+) as an organocatalyst for mediating the reaction between N-substituted imines and ethyl diazoacetate affording excellent yields of N-substituted aziridines.
Palladium- and Platinum-Catalyzed Addition of Aldehydes and Imines with Allylstannanes. Chemoselective Allylation of Imines in the Presence of Aldehydes
Pd(II) or Pt(II) complexes (10 mol %) either at room temperature or at reflux, giving the corresponding homoallylic alcohols 3 in high to good yields. Among the catalysts examined, PtCl2(PPh3)2 gave the best result. No only allyltribitylstannane but also methallyl- and crotyltributylstannane could be utilized in this transition metal catalyzed reaction. Detailed mechanistic studies of the Pd(II)-catalyzed
