摘要：

This work describes the synthesis and the reactivity of three reagents of polyvinylogation 1-3 By condensation with several aldehydes and ketones, these reagents allow the introduction of three or four doubles bonds, leading to polyenals 5-6 in one or two steps with good yields, A thorough study by high field NMR spectroscopy has been realised ; these polyenals show an all trans configuration.
