TRIMETHYLSILYL ISOTHIOCYANATE Chemical Properties,Uses,Production

Chemical Properties

clear colorless to light yellow liquid

Uses

Trimethylsilyl isothiocyanate is used as derivatizing reagent during the synthesis of amino acid thiohydantoins. It participates in ring opening reaction of N-substituted aziridines and cyclohexene oxide.

Uses

Trimethylsilyl isothiocyanate was used as derivatizing reagent during the synthesis of amino acid thiohydantoins.

General Description

Trimethylsilyl isothiocyanate (TMS-ITC) reacts with fullerene-mixed peroxide C60(O)(OOtBu)4 to yield isothiocyanate derivative C60(NCS)(OH)(OOtBu)4. TMS-ITC undergoes condensation with ethyl 2-benzylamino-5-methyl-3-phenylcyclopent-1-enecarboxylate to yield 1-benzyl-5-methyl-7-phenyl-2-thioxo-1,2,3,5,6,7-hexahydrocyclopentapyrimidin-4-one. It participates in ring opening reaction of N-substituted aziridines and cyclohexene oxide.

Purification Methods

The 1H NMR spectrum should have only one peak; if not purify it by repeated fractionation in an all-glass system using a 50cm (4mm internal diameter) column without packing.
