This reaction was discovered early in the development of phosphole chemistry 〈71T5523〉, and has been widely used over the following years (Scheme 80). 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… dylan shiel age
