TRIMETHYLSILYL ISOTHIOCYANATE Chemical Properties,Uses,Production
Chemical Properties
clear colorless to light yellow liquid
Uses
Trimethylsilyl isothiocyanate was used as derivatizing reagent during the synthesis of amino acid thiohydantoins.
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.
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.
