WebThe phospholide moiety of a monophosphaferrocene was acetylated by treatment with acetic anhydride in the presence of trifluoromethylsulfonic acid 〈87ICA93〉. Again the acetylated phosphole was not released from the complex. Benzoyl chloride also was used to benzoylate the phospholide moiety of (286) (Equations (64a) and (64b)). The behavior of the secondary phospholes, those with P−H bond, is dominated by the reactivity of this group. The parent phosphole readily rearranges by migration of H from P to carbon-2, followed by dimerization. Most phospholes are tertiary, typically P-methyl or P-phenyl. The nonaromaticity of these phospholes is manifested in their reactivity but the P−C bonds remain intact. For example, they u… WebNov 29, 2024 · A bis-phospholide framework allows isolation, structural, and spectroscopic characterisation of isostructural lanthanide, uranium, neptunium, and plutonium σ … how did socrates corrupt the young
