概要

• 論文の詳細を見る

• The attempted preparation of thiocarbonyl ylides (I) by the proton abstraction of thiouronium salts (III) has disclosed a fast isomerization of I to enethiols (V) (Y=H) and an alternative desulfurization to enediamines (VII) (Y=Ph), the by-products being olefins (VIII) and sulfides (IX). The second route to I examined consists of the reaction of tetramethylthiourea (II) with diazomalonate, which gives rise to enediamine (VII<SUB>g</SUB>). Rotation about the C=C bond of enediamines is discussed on the basis of IR and NMR spectra.
