Abstract
The compounds listed in tables I and II have been prepared by the reaction schemes A, B and C.
Acid hydrolysis of vinyloxyethyne produces vinyl acetate. Rearrangement of 3‐hydroxy‐3‐methyl‐1‐vinyloxy‐1‐butyne XIV by acid gives the vinyl ester of 2,2‐dimethylacrylic acid XV.

## Abstract Di‐(alk‐1‐ynyl) thioethers IV have been prepared from 2,2′‐dichlorodivinyl thioether II by converting this compound into metallated diethynyl thioether by means of four equivalents of sodamide in liquid ammonia, followed by alkylation. The starting material II was obtained in a high yie
Several alk-l-enyl alkyl ethers were obtained during preparative gas chromatography of acetals derived from saturated and unsaturated fatty aldehydes and methyl, ethyl, propyl and butyl alcohols. Analysis of these substituted vinyl ethers by argentation chromatography, gas-liquid chromatography, inf
Tissues of the starfish Distolasterias nipon contain large amounts of lipids derived from ethanediol ethers. The neutral lipid fraction yielded, by combined column and thin-layer chromatography, an individual compound of the type 1-alk-l'-enyl-2-acyl ethanediol and a group of saturated 1-alkyl-2-acy
