Abstract

1,4-Bis(2,4,6-tri-t-butylphenyl)-1,4-diphosphabutatriene was obtained by the copper-mediated coupling reaction of 1-halo-2-phosphaethenyllithiums. The 1,4-diphosphabutatriene formed mono- and bis-pentacarbonyltungsten complexes, and the X-ray analysis of the bis-tungsten complex revealed end-on type coordination with the trans configuration.
