## Abstract The reaction between epichlorohydrin and ethylthioethynylβlithium affords the enynol V and furfuryl ethyl sulphide VI. The same reaction with ethoxyethynylβlithium, however, produces the epoxy compound VII.

Abstract
In the reaction of oximes I with ethoxyethyne II at 75β90Β° orthoesterlike products III are formed. Some aldoximes, however, are dehydrated to nitriles. The results are summarized in Table I.

## Abstract Ethoxyethyne I readily reacted with an ethereal solution of butynedioic acid V affording a product, C~12~H~16~O~7~, obviously formed from 1 mole of butynedioic acid, two moles of ethoxyethyne and one mole of water. Further investigations revealed that it had the anhydride structure IX.
## Abstract Acetylenic ethers V react with aldehydes in aqueous medium at room temperature to yield the hydroxy esters VII and IX, often together with a small amount of the unsaturated ester VIII. The acetylenic ethers do not react in such a way with ketones and aromatic aldehydes but a similar rea
