  "abstract": "Scalar coupling between nuclei provides some of the most useful information available from an NMR spectrum. While scalar coupling between 31P and 6/7Li may be observed at low temperatures, or in a very small number of cases at room temperature, coupling between 31P and the remaining alkali metal nuclei has remained elusive. The super-bulky chlorophosphane (MeBhp)2PCl (1Cl) provides convenient access to the alkali metal phosphanides {(MeBhp)2P}ML [ML = Li(THF)2·1/2PhMe (1Li), Na(OEt2) (1Na), K(PhMe)·2.5PhMe (1K·Tol), K(THF)3·2PhMe (1K·THF), Rb (1Rb) and Cs(OEt2)·Et2O (1Cs·Et2O)], which crystallise with short M–P distances (except 1K·THF) and trigonal planar phosphorus centres (except 1Na). The structural features of these compounds enable the NMR observation of scalar coupling between heavier alkali metal nuclei and another nucleus (in this case 31P) for the first time.",
