| [Preparation]
Preparative Method of 1,3-Benzodithiolylium tetrafluoroborate: treatment of 2-(3-methylbutoxy)-1,3-benzodithiole with Tetrafluoroboric Acid in
Acetic Anhydride at 0 °C. | [General Description]
1,3-Benzodithiolylium tetrafluoroborate is a carbenium ionic compound. It has been synthesized by reacting 1,3-benzodithiole with trityl tetrafluoroborate. It is widely used as an α-alkylating agent for the enantioselective α-alkylation of aldehydes., The nature of adsorption of 1,3-benzodithiolylium tetrafluoroborate on various carbon nanotubes (CNTs) has been studied. 1,3-Benzodithiolylium tetrafluoroborate reacts with different nucleophilic reagents at the 2-position to form the respective 1,3-benzodithioles. | [storage]
1,3-Benzodithiolylium tetrafluoroborate can be stored in the absence of moisture and light; no toxicity data is
currently available; 1,3-benzodithiol-1-ium perchlorate [32283-21-9] is also known, but poses a risk of
explosion. | [Purification Methods]
1,3-Benzodithiolylium tetrafluoroborate is recrystallized from acetic acid or acetonitrile/ether. |
