## 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
