P. Binger et al., FORMATION AND STRUCTURE OF A NEW DINUCLEAR RHODIUM COMPLEX [(IPR(3)P)RHCL](2)[P(3)C(3)TBU(3)], Chemische Berichte, 128(7), 1995, pp. 737-739
The new dinuclear rhodium complex 4 was synthesized by reaction of [(i
Pr(3)P)(2)RhCl](2) (1) or [(iPr(3)P)(2)(CH2=CH2)RhCl] (2) with 2-tert-
butyl-1-phoshaacetylene (3) in 58% yield. An X-ray analysis reveals th
at in 4 a 1,3,6-triphosphahexadiene-1,6-diyl chain is bound to each of
the two rhodium atoms in an eta(1), eta(3) manner.
