WebAbstract. “Nondissociative” chain walking is a mechanism where an alkylmetal species undergoes rapid β-hydride elimination and reinsertion to move the metal center along the alkyl chain without dissociating an alkene intermediate during the migration process. This digest summarizes the unique characteristics of the nondissociative chain ... WebOct 1, 2024 · The walking strategy of the close-chain multi-legged mechanism is adjusted through the spatial close-chain trunk mechanism. These two single-DoF close-chain mechanisms are designed and coupled to constitute whole close-chain mechanism as the walking platform. The locomotion modes of the trunk are discussed with the mobility …
