Part I. The Stereochemistry Of Carbanions Formed By Base Catalyzed Decomposition Of Azoacetates Part Ii. Anomalous Decarbonylation Of 4 –Substituted Carboxylic Acids With Thionyl Chloride, Tai-Shun Lin

Dissertations

Introduction

Although the stereochemical capabilities of carbonium ions have been extensively investigated, the stereochemical fate of carbanions has been subjected relatively little to systematic scrutiny. The fact that only a limited number of clean-cut sources of carbanions are available has added difficulty to such investigations.

The stereochemical capabilities of carbanions has been extensively and thoroughly examined in recent years by Cram and coworkers. However, the carbanion carbon developed in the reactions employed was bonded in every case to an unsaturated (usually aromatic) group. No fully aliphatic carbanion has been subjected to such a stereochemical study.

The reaction of lead tetraacetate …

Dimethyl Sulfoxide Oxydation Of Hydroxy-Steroids And Studies On The Oxidation Of The 5’–Hydroxy Group Of Nucleosides, Carmen V. Zenarosa Dec 1969

Dimethyl Sulfoxide Oxydation Of Hydroxy-Steroids And Studies On The Oxidation Of The 5’–Hydroxy Group Of Nucleosides, Carmen V. Zenarosa

Dissertations

Introduction

In our earlier work we demonstrated the usefulness of the acidcatalyzed reaction between N-(p -tolyl)diphenylketenimine (21) and dimethyl sulfoxide (DMSO) for the oxidation of secondary alcohols. This was exemplified by the oxidation of 2',3'-O-isopropylideneadenosine and other secondary alcohols.1 We have now extended this procedure to the oxidation of hydroxy-steroids.

Alkynylamines or ynamines can be written in two resonance forms: R-C≡C-N R'2 and R-C=C=NR'2. Because of the close similarity between the latter structure and the structure of a ketenimine (R2C=C=N-R') and the ability of sulfoxide-ketenimine to effect the oxidation of secondary alcohols, we …


Homogenous Catalytic Hydrogenation Of Organic Compounds Using Rhodium-Triarylphosphine Complexes, Jack Lee Parsons Aug 1969

Homogenous Catalytic Hydrogenation Of Organic Compounds Using Rhodium-Triarylphosphine Complexes, Jack Lee Parsons

Dissertations

Introduction

The purpose of this research was to study the homogeneous catalytic hydrogenation of α,β-unsaturated organic compounds containing a wide variety of reducible functional groups. The catalysts to be used were rhodium complexes of triarylphosphines. It was also desired to develop these catalytic systems into practical synthetic methods for the reduction of unsaturated compounds.
