Conditions (in Et2O or THF): 1m (2.5 mmol), Li (6.3 mmol), PheMe2SiH (1.0 mmol) and solvent (25 ml). Conditions (ball milling): 1m (2.5 mmol), Li (5.5 mmol), Et2O (5.5 mmol) and PhMe2SiH (1.0 mmol). Isolated yields are shown. Integrated 1H NMR spectroscopic yields are shown in parentheses. THF, tetrahydrofuran.
