Abstract
Cyclic tris (disubstituted phosphinoborines) of the general formula <FORM:0882532/IV (b)/1> wherein each R1 which may be the same or different, represents an alkyl, cycloalkyl or aryl radical, containing up to six carbon atoms, which radical may be substituted, are made by reacting 1 mole of a tetra-substituted diphosphine disulphide of the general formula R2PS.SPR2 with from 1.5 to 3.5 moles of lithium, sodium or potassium borohydride at an elevated temperature either (a) in the absence of a solvent, at a temperature above the melting point of the disulphide in an inert atmosphere or (b) in the presence of a solvent at a temperature above 150 DEG C. Lithium borohydride is preferred, but good yields are obtainable using sodium or potassium borohydride by using a lithium halide as catalyst. Examples describe the preparation of tris (dimethylphosphinoborine) from tetramethyldiphosphine disulphide and sodium borohydride, and tris (diethylphosphinoborine) from tetraethyldiphosphine disulphide and lithium borohydride.
