Reaction Steps

Under argon and with the exclusion of moisture, 14.0 g of lithium (2.0 mol) are introduced into 250 ml of tetrahydrofuran at room temperature. Following the addition of 1.25 g of naphthalene, 44.8 g (0.25 mol) of dichlorophenylphosphine are added dropwise with stirring at 20-25° C. and, after stirring for 4 h, the black solution is filtered into a three-necked round flask through a frit (G2 porosity) with the exclusion of moisture and under argon as a protective gas. 47.2 g (0.258 mol) of 2,4,6-trimethylbenzoyl chloride are added dropwise at room temperature over the course of 30 minutes with stirring and cooling. Stirring for 2 hours gives the title compound as a red solution in tetrahydrofuran.
