Whakamahinga
Ko te Diethylamino-sulfur trifluoride (DAST) he matū whakapūhau e whakamahia whānuitia ana i roto i te hanga matū waro. He mema nō te whānau (dialkylamino) sulfur trifluoride. Ko te DAST he matū whakapūhau nucleophilic, ka taea te huri i te rōpū hydroxyl waipiro ki te fluorine e rite ana, me ngā aldehydes me ngā ketones ki te difluoride.
