HMDS (1,1,1,3,3,3-Hexamethyldisilazan)

HMDS is weak TMS donor. If used as sole reagent, it is slow and not very effective. After addition of catalytic quantities (e.g., 1 %) of TMCS or as a mixture with TMCS it is a fast and quantitative reagent for trimethylsilylation of organic compounds.


  • Silylation can be applied on many compounds
  • Silylation reagents are easily prepared
  • HMDS reagent mixed with TMCS catalyst shows fast and quantitative reaction


Aprotic solvents like acetonitrile, pyridine, dimethylformamide, carbon disulfide and dimethylacetamide are recommended for use with HMDS.
