Abstract
A wide-bite-angle diphosphinine ligand has been designed and synthesized, which exhibits structural
features for a preferred formation of trans complexes. Due to the linear orientation of the lone-pair electrons
of the phosphorus donors in combination with an appropriate P-P distance, trans coordination toward a
Rh center was observed and the corresponding LRh(CO)I complex could be characterized crystallographically.
Although typical reactivities usually observed for trans complexes were found, reaction of
the diphosphinine with the cis-enforcing precursor [Rh(nbd)2]BF4 did result in the formation of several
species at low temperature, to which cis-structures were attributed.
