查询词典 reactivities

This thesis consists of three main parts of the research work on the syntheses, structures and reactivities of the olefin-coordinated transition metal carbene and carbyne complexes. In chapter 1, on the basis of our previous research works on the reacitivites of the cationic carbyne complexes of transition metals with metalcarbonyl anions, we explored the reactions of the cationic carbyne complexes of manganese (1) and rhenium (2) with polymetalcarbonyl anions, and developed a new method for the preparations of heternuclear trimetal bridging carbyne complexes.

These dendritic NOBIN derived Schiff base ligands have been applied to titanium catalyzed hetero-Diels-Alder reaction of Danishefshy's diene and aldehydes, affording the corresponding 2-substituted 2, 3-dihydro-4H-pyran-4-one in quantitative yields and excellent enantioselectivities (up to 97. 2%ee). Comparing the reactivities and enantioselectivities of reaction catalyzed by the titanium complexes of these Schiff base ligands, it was found that a series of ligands L〓 were superior to the other three series of ligands L〓, L〓 and L〓, a significant positive NLE and a dendrimer effect existed in the L〓 dendritic catalyst system. The disposition of the dendritic wedges and the dendron size in the ligands were observed to have a significant impact on the enantioselectivity of the reaction.
