摘要:
Bis(NHC)-Pd(II) complexes derived from 1,1'-binaphthyl-2,2'-diamine (BINAM) were successfully first used to catalyze the dioxygenation of alkenes under mild conditions tolerant of air and moisture. Cationic NHC-Pd2+ diaquo complex le showed the highest catalytic activity to give 1,2-dioxygenation products with good syn-diastercoselectivity for 1,2-disubstituted alkenes.
