摘要
用ＫＢＨ４与７１７＾＃阴离子交换树脂反应制备了聚合物支载的硼氢化试剂（ＢＥＲ）。在二氯化钯催化下用ＢＥＲ对多种含羰基的化合物分别与苯乙烯的混合液（摩尔比１：１）进行了还原。且对ＢＥＲ还原羰基化合物和苯乙烯的竞争还原规律作了初步探讨。
Polymer-supported borohydride reagents
(BER) have been prepared by reaction of
KBH_4 with 717~# anion exchange rasin.Many
compounds with carbonyl groups((?)C=O)
have been reduced by BER when mixed with
phenylethylene(mol ratio 1:1) over PdCl_2 as
the catalyst.Some regularity of the competition
between carbonyl compounds and phenylethy-
lene in reduction by borohydride anion ex-
change resin(BER) has been preliminari(?)ly in-
vestigated.
