PF3, (CH3)3SiCl -> (CH3)3SiF, and RC(O)Cl -> RC(O)F. Others contain the conversion of (C6H5)3P into (C6H5)3PF2 and of (R3NC(S)S)2 into R2NCF3, R=alkyl. In natural chemistry, fluorides are simply available from alcohols, geminal fluorides RR'CF2 from the respective aldehydes or ketones, and acyl fluorides RC(O)F from carboxylic acides through the use of DAST. simply because DAST is straightforward to address and offers fresh reactions in syntheses, this Gmelin quantity devotes a lot area to the outline of the chemical and actual houses od DAST.
