Lithium N-methylmethanaminide → HCID 13127974, compound

Participants

Reaction Steps

1.00 g (5.16 mmol) of bis(dimethylamino)chlorocarbenium thiocyanate and 0.26 g (5.10 mmol) of lithium dimethylamide are dissolved in 10 ml of acetonitrile under a protective-gas atmosphere (argon). The reaction mixture is stirred for 5 hours at room temperature, and LiCl is subsequently filtered off. The salt LiCl is washed with 2 ml of acetonitrile, and the organic phases are combined. The solvent is distilled off, and the residue is dried under reduced pressure at 7 Pa and 50° C., giving 0.99 g of hexamethylguanidinium thiocyanate as an oil, corresponding to a yield of 94.8%.
