Descrição

Descrição geral

TBAF(pin)₂ is a fluoride–alcohol complex with coordination number four. It can be obtained by reacting pinacol (pin) with tetrabutylammonium fluoride trihydrate (TBAF(H₂O)₃). The geometric structure and bonding of TBAF(pin)₂ have been studied.[1]

Aplicação

Nucleophilic fluorinating reagent is a more convenient crystalline solid for handling and storage compared to tetrabutylammonium fluoride hydrate (Aldrich 241512). As reported by Engle and Gouverneur, these solids display comparable reactivity on similar substrates.
