The reaction of carbonium ions in sulphuric acid with acetylene and substituted acetylenes
Abstract
Treatment of adamantan-1-ol in sulphuric acid with acetylene leads to 1-adamantylacetaldehyde or 1-adamantyl methyl ketone as major product (together with 1-methylhomoadamantan-2-one), depending on the experimental conditions (acid concentration and reaction time). The reactions of the adamantyl, diphenylmethyl, and norbornyl cations with acetylene and substituted acetylenes have been examined.
