Novel synthesis of stable furan and thiophene o-amino thioaldehydes by reaction of o-azido aldehydes with hexamethyldisilathiane
A new synthesis of monomeric o-amino thioaldehydes of thiophene, benzo[b]thiophene, furan and benzo[b]furan by reacting the corresponding o-azido aldehydes with hexamethyldisilathiane in neat acetonitrile and/or in methanol in the presence of hydrochloric acid at room temperature is reported.
