In our hands, this method has never given greater than 5–10% yields, and with activated ketones an entirely different type of reaction occurs; D. J. Burton et. al., J. Amer. Chem. Soc., 88, 5042 (1966)
- The yield was 75% olefin after 50 hours; 70% after 143 hours; 71% after 168 hours; and 68% after 311 hours
