Abstract:
Hepta-tert-butylnonaphosphane {cyclo-(P4Bu3)}2PBu was employed as a ligand in transition metal complexes of iron(0) (1), cobalt(-I) (2), copper(I) (3) and rhodium(I) (4), which are readily formed in moderate to good yields, and an unstable palladium(II) complex (5). The ligand features three different bonding modes (one monodentate (compounds 1 and 2) and two bidentate (compounds 3-5) with formation of four- or six-membered chelate rings), as determined by X-ray diffraction studies. The 31P{1H} NMR spectral data of 1-3 have been determined by automated line-shape analysis.

The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
