Participants

Conditions

Temperature: 125 °C

Procedure

A 300 mL autoclave was charged with acetamide (VII)(11.8 g, 0.2 mole), 95% paraformaldehyde (13.6 g, 0.43 mole), water (6.5 g, 0.36 mole), acetic acid (16.8 g, 0.28 mol. 0.19 g/mL of DME), DME (90 mL) and Co2(CO)8 (4.1 g, 0.012 mole) and pressurized to 1500 psi (10,345 kPa) CO:H2 (95:5) at 25° C. This mixture was heated to 125° C. for 30 min. HPLC analysis of this stream gave a 93% yield of (XVI), 1% (XIV), and 4% (XVIII).

Workup

custompressurized to 1500 psi (10,345 kPa) CO:H2 (95:5) at 25° C
