产品介绍：

Technical Note:

1.A binucleating diphosphine ligand used as a trans-spanning ligand which rigidly links mutually trans coordination sites via e.g. inMCl,(SPANphos) (M= Pa, Pt), Rhs(u-CI)2(CO)(SPANphos), the latter usefui in, for example, the homogeneous catalyti ; carbonylation of methanol to acetic acid.
