Phosphine‐Relayed Aldehyde‐Olefination and Aza‐Wittig Reaction with 2,2,2‐Trifluorodiazoethane |
| |
Abstract: | Phosphine‐relayed olefination and aza‐Wittig reactions of readily available aldehydes with 2,2,2‐trifluorodiazoethane (CF3CHN2) have been realized. This protocol enables the facile construction of a series of trifluoromethylated alkenes and hydrazones in good to high yield under mild conditions. |
