Abstract
A series of 2,3-bis(siloxy)-1,4-bis(diphenylphosphino)butanes SILOPs, possessing various siloxy groups, and their Rh(I) complexes have been prepared. The X-ray structure of a SILOP shows a staggered conformation with two siloxy groups in the anti positions. The X-ray crystal structure of a cationic Rh(I)-SILOP complex, however, shows an anti arrangement of not the two siloxy groups but the two silyl groups with respect to the O–O axis, which reinforces the C2-symmetrical environment around the metal center.
