描述

一般說明

1,3-Benzodithiolylium tetrafluoroborate (BDTF, 1,3-BDYT) is an electrophilic compound.[1] It is a salt of 1,3-benzodithiolylium ion.[2]

1,3-Benzodithiolylium tetrafluoroborate is a carbenium ionic compound.[3] It has been synthesized by reacting 1,3-benzodithiole with trityl tetrafluoroborate.[2] It is widely used as an α-alkylating agent for the enantioselective α-alkylation of aldehydes.[4],[5] The nature of adsorption of 1,3-benzodithiolylium tetrafluoroborate on various carbon nanotubes (CNTs) has been studied.[1] 1,3-Benzodithiolylium tetrafluoroborate reacts with different nucleophilic reagents at the 2-position to form the respective 1,3-benzodithioles.[2]
