Methylmagnesium iodide (MeMgI)
Methylmagnesium iodide (MeMgI) yog siv dav siv cov organic synthesis reagent nrog ntau yam khoom zoo heev. Nws muaj zog nucleophilicity thiab tuaj yeem ua rau muaj ntau yam organic tebchaw, suav nrog cawv, acids, esters, ethers, amines, thiab lwm yam. Qhov tseem ceeb tshaj plaws yog Methylmagnesium iodide (MeMgI) tuaj yeem ua kom tiav cov tshuaj tiv thaiv ntawm kev hloov carbonyl compounds (xws li ketones, aldehydes, acid anhydrides, thiab lwm yam) rau hauv cov cawv sib xws, thiab yog ib qho tseem ceeb reagent hauv tshuaj synthesis. Nws kuj tuaj yeem siv rau hauv kev tsim tshuaj, kev tsim tshuaj zoo, tshuaj tua kab, thiab lwm yam. Tsis tas li ntawd, Methylmagnesium iodide (MeMgI) kuj tseem siv rau hauv kev tshawb fawb biochemical. Nws tuaj yeem siv los sau cov amino acid residues hauv cov protein, uas yog qhov zoo rau kev tshuaj xyuas cov qauv thiab kev ua haujlwm ntawm cov protein.
