After stirring at 00C for 10 min, reaction mixture was stirred at RT for 0.5h and then MeI (0.4 ml) was added. After 45 min, another 5.55 ml of NaHMDS was added at 00C. Again after stirring at RT for 0.5 h, 0.5 ml of MeI was added and the reaction mixture was stirred at RT for 2h. Then the reaction mixture was quenched with ammonium chloride and solvent removed. Then the reaction mixture was diluted with ethyl acetate, acidified with 2N HCl and washed with ether. Aqueous layer was <n="120"/>then basified and extracted with CHCl3. organic layer was dried and evaporated to yield methyl 2-(3-methoxyphenyl)-2-methylpropanoate.

81% General procedure: Inside the glovebox, lithium 2,2,6,6-tetramethylpiperidide (LiTMP, 70.7 mg, 0.48 mmol, 1.2 eq.) was dissolved in toluene (1.5 mL) and carbonyl compound (3, 0.48 mmol, 1.2 eq.) was added. After 15 min of stirring at ambient temperature a solution of Pd(I) iodo dimer (2, 3.5 mg, 0.004 mmol, 1 mol% for aryl iodides; 17.4 mg, 0.02 mmol, 5 mol% for aryl bromides) and aryl halide (4, X = I or Br, 0.4 mmol, 1.0 eq.) in toluene (0.5 mL) was added. After 4-18 h of further stirring at ambient temperature (reaction progress was monitored by GCMS), the crude was directly adsorbed onto silica (washing with diethyl ether) and purified by flash column chromatography.
