Abstract

Triruthenium complex 2 containing a perpendicularly coordinated 1-pentyne ligand, which is one of the key intermediates of the reaction of triruthenium pentahydrido complex 1 with n-pentane, reacts with benzene to yield μ3-benzyne-μ3-pentylidyne complex 5 by C-H bond activation. β-H elimination form the μ3-penytylidyne ligand occurred upon heating to yield μ3-pentenylidene complex 6, which was followed by the formation of closo-ruthenacyclopentadiene complex 8 by the connection of the two hydrocarbyl moieties placed on each face of the triruthenium plane with partial metal-metal bond breaking. Treatment of 8 with pressurized hydrogen resulted in exclusive liberation of n-pentylbonzene, which is difficult to synthesize by conventional Friedel-Crafts alkylation. These sequential transformations correspond to the formation of linear alkylbenzene by the reaction of pentane with benzene on a trimetallic plane.
