BIDENTATE PHOSPHINES OF HETEROARENES - EFFECTIVE STABILIZATION OF THECO-2(CO)(6) FRAGMENT BY 4,6-BIS(DIPHENYLPHOSPHINO)DIBENZOFURAN

Reaction of Co-2(CO)(8) with 4,6-bis(diphenylphosphino)dibenzofuran (1 ) in diethylether gives the dinuclear complex diphenylphosphino)dibenz ofurandicobalthexacarbonyl (2). The solid state structures of 1 and 2 have been established by X-ray crystallography. Low temperature C-13-N MR spectroscopy was used to analyse 2 in solution.
