Abstract

The interaction of W(PhC triple bond CPh)3(CO) with diphenylacetylene promoted alkyne-alkyne coupling resulting in the production of a cyclobutadiene complex. Structural studies using 13C nuclear magnetic resonance spectroscopy were conducted on W(eta4-C4Ph4)(PhC triple bond CPh)2(CO) to determine the crystal properties of the complex. The electronic configuration and reactivity experiments also provided data regarding the geometry of the complexes.

Abstract

The reductive dimerization and thermal rearrangement of biphenylene coordinated to tricarbonylmanganese were investigated. Novel ((eta(super 6)-C12H8)Mn(CO)3)(super +)(BF4)(super -) (1(super +)BF4 (super -))(super 10) in 87% yield were described for this purpose. A diagram was presented in which each manganese atom is linked to three terminal carbonyls and a cyclopentadienyl ligand. The two benzopentalene units C7-C18 and C19-C30 are shown to be planar.
