Abstract
Fluoride-ion-induced reactivity of bromo(phenylthio)methyltrimethylsilane with o-hydroxy benzaldehyde and o-mercaptobenzyl alc. afforded direct and simple access to 2,3-dihydro-2-phenylthio-3-hydroxybenzofuran and 2-phenylthio-3-hydroxy-2,3-dihydrobenzothiophene, respectively. 1-Phenoxy-3-hydroxy-2,3-dihydrobenzo-thiophene could be similarly obtained through a slightly modified procedure.File in questo prodotto:
