Thus we cooperate to study the function and mechanism of this catalyst in the asymmetric
borane
reduction reaction, and the following results are obtained.
Both catalyst -
borane
- ketone adducts and catalyst - alkoxy
borane
adducts have four stable structures.
The structual rule of
borane
were advanced based on the number of above electron, we discussed electron structure of
borane
(http://sentencedict.com/
borane
.html), dense
borane
and hetero—
borane
.
The catalyst is a twisted chair structure and reacts with
borane
at the N site of the catalyst to form catalyst
borane
adduct. The formation reaction is exothermic.
The asymmetric reduction of ketosulfone with
borane
catalyzed by oxazaborolidine is computed by means of the semi-empirical MNDO method.
The chiral oxazaborolidines that formed by the reaction of the new ligands above with
borane
can be used in the asymmetry catalytic reaction prochiral ketones.
Asymmetric
borane
reduction of prochiral ketones is a good process to the synthesis of enantiomerically enriched secondary alcohols.
The poly ( p phenylene
borane
) and poly ( m phenylene
borane
) are synthesized by the modified organometallic route.
Both stereo effect and electron effect of
borane
on the activity of ethylene polymerization were investigated.
