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

1,1,3,3-Tetramethylguanidine (TMG) e na le lits'ebetso tse fapaneng masimong a mangata, haholo-holo tlhahisong ea lintho tse phelang le lits'ebetsong tsa indasteri. E le motheo o matla, e sebelisoa bakeng sa liketso tsa ho tlosa protonation, ho kenyeletsoa le ho tlosa protonation ea li-acid, ho nolofalletsa liphetoho tse fapaneng tsa maiketsetso joalo ka ho kolobisa, ho tlosa le ho nkeloa sebaka ha nucleophilic. TMG e bapala karolo ea bohlokoa ho lokiseng metsoako ea meriana, lik'hemik'hale tsa temo le lik'hemik'hale tse ikhethang. Boleng ba eona bo phahameng bo etsa hore e tšoanelehe hantle bakeng sa ho khothaletsa liketso tse fapaneng tsa ho theha maqhama a carbon-carbon, ho kenyeletsoa le ho kopanya li-polymer, li-resin le lisebelisoa tse sebetsang. Ho feta moo, TMG e sebelisoa tšimong ea catalysis, haholo-holo liketsong tsa tšepe tse susumelitsoeng ke tšepe le lits'ebetsong tsa polymerization, e kenya letsoho tlhahisong ea lik'hemik'hale tse ikhethang le lisebelisoa tse tsoetseng pele. Ntle le karolo ea eona tlhahisong ea lik'hemik'hale, TMG e sebelisoa e le catalyst tlhahisong ea lik'hemik'hale tse ntle le tlhahisong ea metsoako ea meriana. Bokhoni ba eona ba ho nolofatsa tlhahiso ea asymmetric ke ba bohlokoa ho theheng metsoako ea chiral ea bohlokoa ho sibolloeng le nts'etsopele ea lithethefatsi. Ho feta moo, ditshebediso tsa TMG di atoloha ho lokisetsa ditharollo tse ikgethang le di-reagent tse sebediswang ditsamaisong tse fapaneng tsa indasteri. Ka kakaretso, mefuta e mengata ya ditshebediso tsa 1,1,3,3-Tetramethylguanidine e totobatsa bohlokwa ba yona ho ntshetseng pele tshebediso ya dikhemikhale le ditshebediso tsa indasteri.
