1,1,3,3-TetramethylGuanidine CAS:80-70-6

I-1,1,3,3-Tetramethylguanidine (TMG) inezinhlelo zokusebenza ezahlukahlukene emikhakheni eminingi, ikakhulukazi ekuhlanganisweni kwezinto eziphilayo kanye nezinqubo zezimboni. Njengesisekelo esiqinile, isetshenziselwa ukusabela kwe-deprotonation, okuhlanganisa nokususwa kwe-asidi, okuvumela ukuguqulwa okuhlukahlukene kokwenziwa okufana nokujiya, ukususwa, kanye nokufakwa esikhundleni kwe-nucleophilic. I-TMG idlala indima ebalulekile ekulungiseleleni izinto ezisetshenziswa emikhakheni, amakhemikhali ezolimo, kanye namakhemikhali akhethekile. Ukuqina kwayo okuphezulu kwenza ifaneleke kahle ekukhuthazeni ukusabela okuhlukahlukene kwe-carbon-carbon bond-forming, okuhlanganisa ukuhlanganiswa kwama-polymer, ama-resin, nezinto ezisebenzayo. Ngaphezu kwalokho, i-TMG isetshenziswa emkhakheni we-catalysis, ikakhulukazi ekusetshenzisweni kwe-metal-catalyzed kanye nezinqubo ze-polymerization, okufaka isandla ekukhiqizweni kwamakhemikhali akhethekile nezinto ezithuthukisiwe. Ngaphezu kwendima yayo ekuhlanganisweni kwamakhemikhali, i-TMG isetshenziswa njengesikhuthazi ekukhiqizweni kwamakhemikhali amahle nasekukhiqizweni kwamakhemikhali emithi. Amandla ayo okwenza lula ukuhlanganiswa okungalingani abalulekile ekudaleni amakhemikhali e-chiral abalulekile ekutholakaleni nasekuthuthukisweni kwemithi. Ngaphezu kwalokho, ukusetshenziswa kwe-TMG kufinyelela ekulungiseleleni izinyibilikisi ezikhethekile kanye nama-reagent asetshenziswa ezinqubweni ezahlukahlukene zezimboni. Sekukonke, ububanzi bokusetshenziswa kwe-1,1,3,3-Tetramethylguanidine bugcizelela ukubaluleka kwayo ekuthuthukiseni kokubili ukwenziwa kwamakhemikhali kanye nokusetshenziswa kwezimboni.
