## Abstract A number of di‐(alk‐1‐ynyl) thioethers VIII have been synthesized using reaction scheme 1. Except for diethynyl ether VI the compounds are relatively stable. Reaction scheme 2 has been used to synthesize di‐(prop‐1‐ynyl) ether, a substance exploding at room temperature. An attempt to p

## Abstract The compounds mentioned in the title are obtained conveniently from aldehydes as outlined in the reaction schemes on this and on the following page.
## 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 The cyclobutenone ethers V listed in table I have been prepared from 1‐alkoxy‐1‐alkynes and ketene.
## Abstract Aldehydes can be converted into 1‐alkylthio‐1‐alkenes II (thioenol ethers) __via__ either α‐chlorothioethers I by elimination of hydrogen chloride or, better, thioacetals VI by acid catalysed elimination of thiol. Bromination of the thioenol ethers II followed by subsequent dehydrobromi
