In this chapter, the MPV reactions catalyzed by alkoxy dysprosium is used to the reduction of prochiral ketones. The chiral alkoxy catalyst was prepared by chiral binaphthol and Dy 〓.

最后还将烷氧基镝催化下的MPV还原反应应用于潜手性酮的不对称还原，利用光学活性的联萘酚制备了手性烷氧基催化剂，结果表明该催化剂可有效地催化潜手性酮的不对称MPV还原。

In order to improve the luminescence and thermal performance of asymmetric ROPPVs, a series of poly derivatives with asymmetric alkoxyl substituents/ nanometer semiconductor composites were synthesized through dehydrochlorination in-situ polymerization.

托叶完全抱茎；全缘的叶片，对称或不对称的，边缘通常齿；蜡腺体在基出主脉腋处，通常也在其他脉腋内或在节上。

As mentioned above, this dissertation can be divided into two parts. One is devoted to study the high resolution ro-vibrational spectra of some asymmetry top molecules, such as D〓O and DOCl. Another is about studying anharmonic force field and vibrational intensities of some symmetry top molecules by quantum chemistry method, such as SiHCl〓 and AsH〓.

因此本论文的工作以此为脉络分为两个部分，第一部分以D〓O和DOCl分子为体系，研究非对称陀螺分子的高分辨振转光谱；第二部分以对称陀螺SiHCl〓和AsH〓分子为体系，用量子化学计算的方法研究了小分子的非谐性力场和振动光谱强度。
