General description

1-Trimethylsilyl-1-hexyne is a trialkylsilylalkyne. Tetrabutylammonium fluoride (TBAF) catalyzed conversion of 1-trimethylsilyl-1-hexyne to corresponding propargylic alcohol is reported. Pd(OAc)2/L‚ HCl-catalyzed Sonogashira coupling reaction of aryl bromide with 1-trimethylsilyl-1-hexyne has been reported.

Application

1-Trimethylsilyl-1-hexyne may be used in the preparation of enynes by coupling with vinyl triflates or aryl iodide using silver salt and Pd(PPh3)4 as catalyst. It may be used in the preparation of functionalised durene and isodurene derivatives.
