Application

N,N-Dimethyltrimethylsilylamine can be used as a reactant to prepare:
  • Trifluoromethylacetophenone-N,N-dimethyltrimethylsilylamine adduct, which is used as an efficient reagent for nucleophilic trifluoromethylation of carbonyl and the imine group.
  • (Dimethylamino)sulfur trifluoride (Me-DAST), which is employed as a deoxofluorinating agent for the conversion of aliphatic alcohols into their corresponding fluorides.
  • Nucleoside phosphoramidites by reacting with alkyloxy (or aryloxy)-triazolylphosphine and deoxynucleoside.

It can also be used as a silylating agent in chemical synthesis.
