Sulfur dioxide is not only a useful building block in a synthetic organic chemistry, but due to its high polarity and Lewis acid properties liquid SO2 can be used as a strongly ionizing solvent, especially, for organic transformations that involve ionic intermediates. Herein we report application of liquid SO2 as a reaction media for various alkyne transformations via vinyl carbenium ion intermediate that is quenched with nucleophiles like water, halide and triflate.
