Reactions of malononitrile with 3-(2-alkenoyl)-2-oxazolidinones or 1-(2-alkenoyl)-4-bromo-3,5-dimethylpyrazoles can be doubly activated by the use of catalytic amounts (10 mol% each) of both (R,R)-DBFOX/Phโ€ขNi(ClO 4 ) 2 โ€ข3H 2 O and amines, to give the Michael adducts in high chemical yields with sati
