Ib pawg trimethylsilyl (abbreviated TMS) yog ib pab pawg ua haujlwm hauv organic chemistry . Cov pab pawg no muaj peb pawg methyl sib txuas rau silicon atom [−Si(CH3)3], uas yog nyob rau hauv lem bonded rau tus so ntawm ib tug molecule.

Ntawm no, TMSCl yog dab tsi?

Trimethylsilyl chloride, tseem hu ua chlorotrimethylsilane yog ib qho organosilicon compound (silyl halide), nrog rau cov mis (CH3)3SiCl, feem ntau abbreviated Me3SiCl lub TMSCl . Nws yog cov kua tsis muaj xim tsis muaj xim uas ruaj khov thaum tsis muaj dej. Nws yog dav siv hauv organic chemistry.

Tsis tas li ntawd, dab tsi yog kev tiv thaiv pawg hauv organic chemistry? A tiv thaiv pab pawg los yog pab pawg tiv thaiv yog nkag mus rau hauv molecule los ntawm tshuaj kev hloov kho ntawm kev ua haujlwm pab pawg kom tau txais chemoselectivity nyob rau tom ntej tshuaj tshuaj tiv thaiv. Nws plays lub luag haujlwm tseem ceeb hauv multistep organic synthesis. Lub acetal yog hu ua a tiv thaiv pab pawg rau carbonyl.

Tib neeg kuj nug, OTBS chemistry yog dab tsi?

Silyl ethers yog ib pawg ntawm tshuaj cov tebchaw uas muaj cov atom silicon covalently bonded rau ib pawg alkoxy. Cov qauv dav dav yog R1R2R3Si-O-R4 qhov twg R4 yog ib pawg alkyl lossis pawg aryl.

Koj yuav tiv thaiv cawv li cas?

Piv txwv

  1. Cov pab pawg tiv thaiv silyl ether tuaj yeem raug tshem tawm los ntawm cov tshuaj tiv thaiv nrog cov kua qaub aqueous lossis fluoride ion.
  2. Los ntawm kev siv cov pab pawg tiv thaiv Grignad reagent tuaj yeem tsim thiab ua rau muaj kev cuam tshuam ntawm cov cawv halo. 1) Tiv thaiv Cawv.
  3. 2) Tsim cov Grignard Reagent.
  4. 3) Ua qhov Grignard Reaction.
  5. 4) Kev tiv thaiv.
