The only example of Si H M agostic interaction supported by a phosphorus bridge was discovered by Driess et al. in the complexation of a silylated triphosphine ligand to a chromium tricarbonyl complex [Eq. (20)].143,144 A bigger metal (M = Mo) or smaller substituent at silicon (R = Ph) leads to the normal triphosphine complexes. The presence of a Si H "M interaction in 59 is deduced from the lack of C3 symmetry (evident from NMR), the red shift of the IR band for the coordinated Si-H bond (1994 cm-1 vs. 2142 cm-1), and the observation of a reduced Si-H coupling (135.7 Hz for the coordinated Si-H bond vs. 210.9 and 228.6 Hz for the free Si-H bonds). The X-ray structure determination of 59 shows that one of the phosphine ligands is tilted away from the chromium atom so that the...

Electrochemical studies of [Pd(triphosphine)(CH3CN)](BF 2 complexes were carried out under both catalytic and noncatalytic conditions to probe mechanistic aspects of CO2 reduction. The mechanism that we have proposed for this catalytic reaction is outlined in Scheme 1. In this scheme, L represents a triphosphine ligand and solv represents a solvent molecule such as DMF or acetonitrile. The data supporting the various steps shown will be summarized next. 

The three triphosphine ligands are PhP(CH2CH2PPh2)2, etp PhP(CH2CH2-CH2PPh2)2, ttp and CH3C(CH2PPh2)3, tripod.
