Abstract:The acid-catalyzed dehydration of
regioisomeric methylcyclohexanols
is a classic organic chemistry experiment featured in a variety of
laboratory textbooks and literature. The mechanistic details of this
reaction have received an inconsistent and occasionally inaccurate
treatment, wherein the reaction has been described as a mix of E1,
E2-like, acid-catalyzed E2, and base-catalyzed E2 processes. We provide
an overview of how this reaction has been represented in the chemistry
education literature and describe … Show more
“…Dehydration of alcohols typically proceeds in the presence of strong Brønsted acid catalysts with an E2 mechanism (primary alcohols) or E1 mechanism (secondary and tertiary alcohols). [13][14][15] Brønstedacid-catalyzed dehydration of alcohols is a classical reaction explained in basic textbooks in general chemistry. Sulfuric acid is a typical homogeneous catalyst.…”
Chemical syntheses of industrially important olefins and unsaturated oxygenates from biomass are reviewed. Their syntheses are discussed in two aspects: common key reactions and target molecules grouped by carbon number....
