摘要：

The reduction of alpha,beta-unsaturated: chromium(0) carbenes 1 and 4 by NaBH4 gives vinyl ethers 2 and / or. allyl ethers 3. Deuterium-labeling studies demonstrate that the reaction occurs by the initial addition of hydride to the carbene carbon, followed by 1,3-rearrangement of the metal center and protonation (for complexes 1), or by a new hydride addition on the allenyl intermediate 8, and subsequent protonation (for complexes 4).
