Tšebeliso
Trimethyl borate ke sesebelisoa se thusang tlhahisong ea lintho tse phelang. E ameha tlhahisong ea li-resin, boka le pente 'me e sebetsa e le moemeli oa methylation. Jwalo ka mohloli oa boron, Trimethyl borate e sebelisetsoa ho lokisa li-retant tsa mollo, li-anti-oxidant le li-inhibitor tsa mafome. E arabela le li-reagent tsa Grignard tse lateloang ke hydrolysis ho lokisa boronic acid. E boetse e sebelisoa e le selelekela sa li-ester tsa borate, tse sebelisoang karabelong ea ho kopanya ea Suzuki. E sebelisoa e le khase ea ho lemoha neutron ha ho na le counter ea scintillation; e le selelekela sa liketso tsa diborane.
Trimethyl borate e arabela ka reagent ea Grignard kapa metsoako ea organolithium ho hlahisa dimethyl boronate, tseo ka mor'a kalafo ea asiti ea metsi li fanang ka li-acid tsa boronic tse tsamaellanang. Li-acid tsa boronic kapa li-ester tse hlahang ke li-intermediate tse thusang liketsong tse fapaneng tsa ho kopanya tse kang ho kopanya Suzuki le ho kopanya Chan-Lam. E boetse e sebelisoa ho lokiseng sodium borohydride.
Ho paka le ho Romela
180KG/Moropa kapa ho ya ka ditlhoko tsa bareki.
