## Abstract The addition of electrophilic reagents to ethyl (ethylthio)propynoate II occurs at carbon atom 2. Uncharged nucleophilic reagents (amines) are also added at carbon atom 2, but charged nucleophiles (ethoxide ion and the carbanion of malonic ester) interact at carbon atom 3. Additions to

## Abstract Acetylenic ethers V react with aldehydes in aqueous medium at room temperature to yield the hydroxy esters VII and IX, often together with a small amount of the unsaturated ester VIII. The acetylenic ethers do not react in such a way with ketones and aromatic aldehydes but a similar rea

## Abstract The thermal decomposition of some 1‐ethoxyvinyl esters is described. The first step of the decomposition is rearrangement to a β‐keto ester, the enolic form of which is subsequently acylated by the 1‐ethoxyvinyl ester.
