General description
Trimethyl phosphate is an excellent dipolar aprotic solvent that is used as a methylating agent and acid scavenger in many organic transformations.
Application
Trimethyl phosphate can be used as a methylating agent for the:
- Solvent-free o-methylation of phenolic compounds to synthesize methyl aryl ethers.
- S-methylation of aryl/alkyl thiols to synthesize S-methylated product in the presence of Ca(OH)2 as a base.

In ultralow magnetic fields, liquid state nuclear magnetic resonance (NMR) spectra of homonuclear spin systems exhibit line widths dominated by their natural lifetime. Chemical shifts become negligible, and heteronuclear NMR spectra show predominantly the electron-mediated field-independent J-coupling. However, weak polarization

Threshold collision-induced dissociation techniques are employed to determine the bond dissociation energies (BDEs) of complexes of alkali metal cations to trimethyl phosphate, TMP. Endothermic loss of the intact TMP ligand is the only dissociation pathway observed for all complexes. Theoretical
