Cobalt(II) acetate tetrahydrate → Cobalt diacetate

Participants

Reaction Steps

The reaction was carried out in a glove box and solvents were degassed prior to use. The polymer 4 (95 mg, 0.16 mmol) was dissolved in dichloromethane (2 mL) in a vial charged with a stir bar. A solution of cobalt acetate tetrahydrate (49.8 mg, 0.20 mmol) in methanol (2 mL) was added slowly to the vial, resulting in precipitation of a red-brown powder. After the suspension was stirred at rt for 3 h, additional methanol (6 mL) was added to precipitate more solid. The solid was collected by filtration, washed with 1/10 dichloromethane/methanol (2×10 mL) and methanol (10 mL), and dried under high vacuum to give the desired product Co(II)(4) (99 mg, 95%). Using a similar procedure, Co(II)(2), Co(II)(3), Co(II)(5), Co(II)(6), and Co(II)(7) were synthesized.
