摘要: (1; R = tert-Bu) (tert-BAE) [5815-08-7] C9H22N2O (MW 174.33) InChI = 1S/C9H22N2O/c1-9(2,3)12-8(10(4)5)11(6)7/h8H,1-7H3 InChIKey = HXRAMSFGUAOAJR-UHFFFAOYSA-N (2; R = Me) (MAE) [1186-70-5] C6H16N2O (MW 132.24) InChI = 1S/C6H16N2O/c1-7(2)6(9-5)8(3)4/h6H,1-5H3 InChIKey = NCIMAYPZWJQYGN-UHFFFAOYSA-N (aminal esters reactive as aminomethylenating reagents (formylating reagents) for CH2- and NH2-acidic compounds. The tert-butyl analog is somewhat more than the methyl derivative; bis(dimethylamino)carbene can be generated from both compounds) Alternate Name: Bredereck's reagent. Physical Data: (1) bp 50–52 °C/12 mmHg; n20D = 1.4250. (2) 128 °C/760 32–33 °C/25 n20D = 1.4158. Solubility: miscible with nonpolar aprotic waterfree solvents (benzene, toluene, cyclohexane, diethyl ether, etc.); react protic like water (hydrolysis to DMF) or alcohols (alcoholysis affords DMF acetals). Even common acetonitrile acetone which are weakly CH-acidic aminal on heating. Form Supplied in: colorless weak yellow, strong amine-smelling liquids. Analysis of Reagent Purity: the best method 1H NMR spectroscopic examination a neat sample. Handling, Storage, Precautions: both compounds should handled in fume hood, strict exclusion atmospheric moisture. They stored tightly sealed containers refrigerator under an atmosphere dry nitrogen argon.
