英語使用場景

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 - alkoxyborane 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.
