at phosphorus was dependent on the ligand used. For example, when a stoichiometric reaction between PCl3 and thiophene-3,4 diyldimethaneamine (R = Mes) was carried out, the synthesis of a bis-substituted diphosphino- product was isolated. If the R = Dipp ligand derivative was employed, both a 2:1 and 1:1 stoichiometric reaction between PCl3 and the diamine was observed. Nevertheless, the cyclic di
