Rules for ring closure
TL;DR: The endocyclic closure of nucleophilic centres to polarized double bonds to give five-membered rings is impeded by restrictions of geometry; these restrictions can be overcome in acid through the generation of oxonium or protonated forms.

TL;DR: In this article, the C-Si bonds in organosilicon fluorides, K 2 (RSiF 5 ] and R n SiF 4-n, are cleaved by m-chloroperbenzoic acid (MCPBA) in DMF to give the corresponding alcohols in high yields.
