Allyl borates: a novel class of polyhomologation initiators

Abstract

Allyl borates, a new class of monofunctional polyhomologation initiators, are reported. These monofunctional initiators are less sensitive and more effective towards polymethylene-based architectures. As an example, the synthesis of α-vinyl-ω-hydroxypolymethylenes is given. By designing/synthesizing different allylic borate initiators, and using ¹H and ¹¹B NMR spectroscopy, the initiation mechanism was elucidated.
