文摘

Hydroxy-CNT were modified with optically active α-amino acids. The resulting chiral derivatives were directly palladated with Pd₂dba₃ and used to catalyze the hydrogenation of α-acetamidostyrene and α-phenylcinnamic acid as well as the hydroarylation of norbornene with iodoarenes. All the catalytic reactions afforded products containing a new chiral carbon center in high yields, though as racemates. Apparently, asymmetric induction is precluded because the palladium sites on the CNT surface are spatially apart from the chiral carbon centers in amino acid groups.
