✦ Synopsis

Abstract

The isomeric allenyl thioethers, III, are produced in good yield by treating 1‐ethylthio‐1‐alkynes, I, with an equivalent amount of sodamide in liquid ammonia, followed by hydrolysis of the reaction mixture.

The corresponding allenyl thioethers alkylated in the 1‐position, IV, are obtained, also in good yield, by adding primary or secondary alkyl halides to the reaction product of sodamide and 1‐ethylthio‐1‐alkynes, I.

## Abstract Ethoxyethyne slowly adds diazomethane to yield 4‐ethoxypyrazole I, the structure of which has been proved by synthesis from 1,1,2,3,3‐pentaethoxypropane IV and hydrazine. Ethylthioethyne V, on the contrary, is converted by diazomethane into 3‐ethylthiopyrazole VI, the structure of which

## 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
