J. Nie et al., COPPER(II)BIS((TRIFLUOROMETHYL)SULFONYL)AMIDE - A NOVEL LEWIS-ACID CATALYST IN DIELS-ALDER REACTIONS OF CYCLOPENTADIENE WITH METHYL VINYL KETONE, Catalysis today, 36(1), 1997, pp. 81-84
Copper(II) salt of weakly coordinating bis((trifluoromethyl)sulfonyl)a
mide anion was newly prepared. A remarkable catalytic effect of the co
pper salt Cu(NTf2)(2) was demonstrated in the Diels-Alder reactions of
cyclopentadiene with methyl vinyl ketone in CH2Cl2 in comparison with
other metal salts.
