摘要

RCu · BF 3 , generated in situ from Grignard reagents, CuI, and BF 3 · OEt 2 , added to aldimines containing α-hydrogens to afford secondary amines in good yields. Boron trifluoride complex of dialkylcuprate gave essentially the same result with wider application. ... Bull. Soc. Chim. Fr. (952), p. 1964 J. Org. Chem., 45 (1980), p. 1515 J. Am. Chem.
