YieldReaction ConditionsOperation in experiment
59% With potassium acetate;(1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; In N,N-dimethyl-formamide; at 95℃; for 3h;Inert atmosphere; Step 1. 2-(Chroman-6-yl)-4,4,5,5-tetramethyl-l ,3,2-dioxaborolaneTo a solution of <strong>[3875-78-3]6-bromochroman</strong> (400 mg, 1.88 mmol) in N,N-dimethylformamide (50 mL) was added 4,4,4',4',5,5,5',5'-octamethyl-2,2'-bi(l,3,2-dioxaborolane) (620 mg, 2.44 mmol), KOAc (552.1 mg, 5.63 mmol) and Pd(dppf)Cl2 (155 mg, 0.19 mmol) with stirring for 3 h at 95C maintained with an inert atmosphere of nitrogen in an oil bath. The reaction mixture was diluted with water, extracted with ethyl acetate (80 mL x 3) and the organic layers combined, dried over anhydrous magnesium sulfate, concentrated under vacuum to give the residue, which was applied onto a silica gel column with 1 % ethyl acetate in petroleum ether to afford 2-(chroman-6-yl)-4,4,5,5-tetramethyl-l,3,2-dioxaborolane as colorless oil (320 mg, 59%).*H-NMR (300 MHz, CDC13): delta 7.54 (d, J = 7.5 Hz, 2H), 6.78 (d, J = 8.4 Hz, 1H), 4.19 - 4.23 (t, J = 5.4 Hz, 2H), 2.78 - 2.83 (t, J = 6.3 Hz, 2H), 1.98 - 2.05 (m, 2H), 1.28 (s,12H)
