General description

Trimethylamine N-oxide is an organic compound that belongs to the class of amine oxides. It is generally found in the tissues of marine organisms, wherein it helps protect them from harsh conditions like salinity, hydrostatic pressure, temperature, and high urea.

Application

Trimethylamine N-oxide can be used:
  • As a demetallation and decarbonylation reagent for organometallic compounds.
  • To prepare azomethine ylide by reaction with lithium di-isopropylamide. This, in turn, may be reacted with simple alkenes to obtain corresponding pyrrolidines.
  • To mediate the conversion of thiols to disulfides.
