Hydride and halide anions readily replace the acetonitrile ligand in the diruthenium μ-allenyl complex 3b. The hydride can successively migrate to the Cα carbon of the allenyl moiety, and then to Cβ, affording 9 as the most stable product. The μ-vinyl-chlorocarbene adduct 10 is believed to be formed from 4b by chloride migration to Cα and hydrogen migration from Cα to Cβ.

Abstract
Hydride and halide anions readily replace the acetonitrile ligand in the diruthenium μ-allenyl complex 3b. The hydride can successively migrate to the Cα carbon of the allenyl moiety, and then to Cβ, affording 9 as the most stable product. The μ-vinyl-chlorocarbene adduct 10 is believed to be formed from 4b by chloride migration to Cα and hydrogen migration from Cα to Cβ.File in questo prodotto:
