Hoʻohana
ʻO Diethylamino-sulfur trifluoride (DAST) kahi mea hoʻohui fluorination i hoʻohana nui ʻia i ka synthesis organik. He lālā ia o ka ʻohana (dialkylamino) sulfur trifluoride. ʻO DAST kahi mea hoʻohui fluorination nucleophilic, hiki ke hoʻololi i ka hui hydroxyl waiʻona i loko o ka fluorine like a me nā aldehydes a me nā ketones i loko o difluoride.
