Acetylene studies. IV. Dehydration of dialkylethynylcarbinols

Abstract The direction of the dehydration in unsymmetrically substituted dialkylethynylcarbinols has been studied, with the help of infra‐red spectra, for isobutylethynylmethylcarbinol; for comparison, the dehydration of diethylethynylcarbinol has been investigated, in which a non‐conjugated hydrocarbon is one of the dehydration products.
