Aldehydes example overview

In this paper we give an overview on the partial oxidation of primary and secondary alcohols to ketones, aldehydes or acids. The influence of promotion on catalyst deactivation will be illustrated using the example of a 5 wt% Pt/alumina partially covered by Bi. 

A variety of compounds cannot be prepared by direct nucleophilic F-fluorination. When high specific activity is required and electrophilic fluorination thus is impossible, labeling is often carried out by a multistep route using small reactive intermediates, often named secondary labeling precursors or prosthetic groups. A whole battery of these F-labeled intermediates was investigated and prepared, such as amines, alcohols, aldehydes, ketones, carboxylic acids, esters, and halides. Since a quantitative overview about these synthons is outside the scope of this chapter, only some examples are discussed. 

Olefins (LAOS - linear alpha olefins) are useful and versatile intermediates for the synthesis of many industrially relevant substances. Examples include co-monomers for polyethylene production, alcohols, aldehydes, carboxylic acids, or sulfonates (Dixon et al., 2004). Table 6.16.1 gives an overview of the most important applications and demonstrates that the applications of the different 1-olefins depend strongly on their chain lengths.
