摘要:

The 1,3-dipolar cycloaddition of 2- and 3-benzothiopheneazide with (trimethyl-sily1)acetylene to yield 1,2,3-triazoles has been studied at pressures up to 1GPa. The kinetics as a function of pressure was followed interfacing a diamond anvil cell to a FTIR spectrometer. Alike with aryl azides, the rate of reaction was found to increase logarithmically with pressure with a yield close to quantitative.
