In view of the commercial availability of cer- tain derivatives of ethylene glycol commonly known as Cellosolves and Carbitols, it was pro- posed to investigate the preparation and proper- ties of acetylenic compounds derived from these starting materials. This group of compounds, the l-alkoxy-3-butynes, provides not only a new type of acetylene for investigation but also fur- nishes a starting point for further syntheses since the terminal hydrogen of the chain is quite ...
