Polyhedral Species—Nuclei Other than Boron

Polyhedral Species— Nuclei Other than Boron 

This area is reviewed in more detail elsewhere, but important points merit brief mention here. Some aspects of coupling constant behavior are in Section 3.3.4 above. B decoupling and other multiple resonance experiments are of considerable use in this area (for example Refs. 29-32, 89, 109, 145, 151, 152, 156, 166, etc.), as is the phenomenon of thermal decoupling.  

Some P data for phosphaboranes, i.e., species that contain an endo-bound phosphorus atom as part of the cluster, are in Refs. 112 and 154b. For pendant exobound tertiary phosphine ligands 5( P) values are similar to those for the same 

Although metallaborane and metallacarborane chemistry is extensive, little information is available on metal nuclear shielding in these compounds, and is essentially limited to some nice work on Be, some isolated Pt chemical shifts, a ( Y) datum for [(thf)2YBjHi2], and a ( Zr) datum for [ZrB4Hie]. Very recent work has included 295 (193-195) 453 (188) H9sn.(i 5)
