| N,N-DiMethylMethyleneaMMoniuM Iodide Usage And Synthesis |
| Chemical Properties | CREAM TO YELLOW CRYSTALLINE POWDER | | Uses | In organic synthesis. | | Uses | (N,N-Dimethyl)methyleneammonium iodide is a useful reagent for many synthetic applications like aminomethylation. It is also essential for the conversion of ketones to α, β-unsaturated enones. It is utilized to prepare derivatives of the type RCH2N(CH3)2. It is extensively used in medicines like painkillers and sedatives- Tramadol hydrochloride intermediate viz. 2-dimethylamine methylcyclohexanone. It is also employed in reactive dyes, synthesized spices. It plays an essential role in Mannich reactions. | | General Description | N,N-Dimethylmethyleneiminium iodide is useful reagent for many synthetic applications, especially aminomethylation and conversion of ketones to α,β?unsaturated enones. | | Synthesis | The mixture of trimethylamine, diiodomethane, dioxane and absolute ethanol was placed in the dark to react at room temperature for 100 h, the resulting crystals were collected by filtration, washed with ethanol and ether in turn, and dried under vacuum at 70 °C to obtain iodomethyl trimethylMethylammonium iodide. It was heated with sulfolane and kept at 160 °C for 12 min. The precipitated crystals were collected by filtration, washed with carbon tetrachloride, and vacuum dried at 50 °C to obtain N,N-DiMethylMethyleneaMMoniuM Iodide. |
