Phosphorus compounds, labile

In aquatic environments, substantial amounts of inositol phosphates have been reported in lake waters (McKelvie et ah, 1995) and estuarine sediments (Suzumura and Kamatani, 1995). Other more labile organic phosphorus compounds, such as phosphate diesters and adenosine triphosphate, which account for only a small proportion of the total organic phosphorus in soils, are particularly important in lake and marine sediments (Carman et ah, 2000), as are labile polyphosphates (Hupfer et ah, 1995). 

The effect of insulin on phosphorus metabolism in muscle was studied in three ways the incorporation of radioactive phosphorus in various phosphorylated compounds, balance studies in isolated diaphragms in which inorganic total phosphorus and labile phosphorus were measured as well as the rate of glycogen synthesis, and in vitro phosphorylation studies of creatine. 

The behavior in the same reaction of several phosphorus compounds with a labile P-H bond was investigated under a variety of conditions (homogeneous, heterogeneous, heating, photochemical, sonochemical, "dry medium").Qf these, sonication appears to be especially efficient and selective, but the system is made complex by the important reactivity differences between the various substrates used (phosphonate, phosphine, phosphine oxide, or sulfide) and no general rule can be formulated.

In addition to oxygen, the phosphorus can be tied to the backbone through nitrogen. Indeed, this was one of the earliest variations of the DIOP family (see Section 23.3) with PNNP (45) [22, 280, 287]. Care must be taken to avoid hydrolysis of the labile P-N bonds [22, 288]. Other examples of nitrogen-linked compounds are BDPAB (46 and 47) and its derivatives (Fig. 23.4). These ligands are clearly variations of the BINAP series [289-291].
