A mild and facile Peterson olefination has been developed employing low catalyst loading of the Brønsted acid HNTf2. The reactions are typically performed at room temperature, with the reaction tolerant to a range of useful functionalities. Furthermore, we have extended this methodology to the synthesis of enynes.
