To a solution of acetato complex 3 (26.7 mg, 0.04 mmol) in CH2Cl2 (5 mL), a solution of 2-(diphenylphosphino)benzoic acid (24.6 mg, 0.08 mmol) in CH2Cl2 (5 mL) was added. The reaction mixture was stirred at ambient temperature for 5 h. The resulting solution was concentrated to half of the initial volume, and n-hexane(20 mL) was added. The precipitate was collected and dried in vacuo affording the product as a white powder (14.7 mg, 0.03 mmol, 75percent). 1H NMR (600 MHz, CDCl3):d 9.14 (s, 1 H, Hh), 8.30?8.28 (m, 1 H, Dpb?H), 7.71 (t, 1H, Hf, 3JH,H = 6 Hz), 7.48?7.26 (m, 12 H, He, Hg, Dpb?H), 6.95 (d, 1 H, Hd, 3JH,H = 6 Hz), 6.85?6.80 (m, 2 H, Ha,Dpb?H), 6.72 (t, 1 H, Hc, 3JH,H = 6 Hz), 6.36 (t, 1 H, Hb,3JH,H = 6 Hz), 4.28 (br s, 2 H, CH2). 13C NMR (150 MHz,CDCl3): d 170.5 (d, CO, 3JC,P = 4.2 Hz), 158.7 (Ck), 151.3(Ch), 148.2 (d, Cj, 2JC,P = 1.5 Hz), 143.7 (d, Dpb?C,JC,P = 13 Hz), 140.9 (d, Ca, 3JC,P = 12 Hz), 139.4 (Cf),138.8 (Ci), 135.3 (d, Dpb?C, JC,P = 13 Hz), 133.8 (d,Dpb?C, JC,P = 9 Hz), 132.1 (d, Dpb?C, JC,P = 4.5 Hz),131.4 (d, Dpb?C, JC,P = 1.5 Hz), 130.1 (d, Dpb?C,JC,P = 9 Hz), 129.2, 128.5, 128.2 (Dpb?C), 127.1 (Cd),126.0 (d, Cb, 4JC,P = 4.5 Hz), 124.3 (Cc), 124.1 (d, Ce,4JC,P = 3 Hz), 123.0 (d, Cg, 4JC,P = 3 Hz), 49.9 (CH2).31P NMR (100 MHz, CDCl3): d 33.2 (s, PDbp).
