Alcohols aliphatic, acetamidation

This type of expansion very frequently occurs among long-chain aliphatic compounds. All the fatty acids show it, and the expansion is very similar with the a-bromo-acids, the nitriles, alcohols, amides, ureas, oximes, amines, and acetamides. In all these series the expanded film is probably liquid, with a definite surface-vapour pressure, and the area is about 48 sq. A. at the lowest compression. Some other substances form similar films but of different areas the p-alkyl phenols tend to 39 sq. A. (j), and the a-monoglycerides (j) and the a-glyceryl ethers1 of long-chain alcohols,... 

Examples of gold-catalyzed carbonylation of amines and olefins exist related to the activation of carbonyl. The first case involves the formation of carbamates from anilines and CO in the presence of alcohols or the production of acetamides from aliphatic amines. In these examples, Au(I) (usually [AuCl(PPh3)]) catalysts are preferred. For the carbonylation of olefins, gold(I) carbonyls are prepared in situ in sulfiu ic acid media to afford carboxyhc acids. ...
