The
cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)-cyclopentan
e/[PdCl(C3H5)]2 system catalyses allylic
amination in good yields with a very high substrate/catalyst ratio; a
turnover number of 680 000 and a turnover frequency of 8125
h−1 can be obtained for the addition of dipropylamine to
allyl acetate in the presence of this catalyst.
顺式、顺式、顺式-1,2,3,4-四(二苯基膦甲基)环戊烷/[PdCl(C3H5)]2系统在良好的产率下催化烯丙基胺化反应,具有很高的底物/催化剂比率;在该催化剂存在下,将二丙胺加成到乙酸烯丙酯中,可以获得680,000的周转数和8125 h−1的周转频率。
