diethyl(3-pyridyl)borane CAS:89878-14-8

Diethyl(3-pyridyl)borane e na le dikopo tse ngata mafapheng a fapaneng a dikhemikhale le saense ka lebaka la reactivity ya yona e ikgethang le thepa ya sebopeho. Ka ho kopanya dintho tse phelang, e sebetsa e le reagent ya bohlokwa bakeng sa tshebetso ya dimolek'hule tsa tlhaho, e nolofalletsang ho kenngwa ha dihlopha tse nang le boron ka hara dibopeho tse rarahaneng. Sena se nolofalletsa ho kopanngwa ha di-intermediate tsa meriana, dikhemikhale tsa temo, le dikhemikhale tse ikgethang, e fa borakhemistri sesebediswa se feto-fetohang bakeng sa ho rala le ho fihlella meralo e fapaneng ya dimolek'hule. Ho feta moo, Diethyl(3-pyridyl)borane e bapala karolo ya bohlokwa diphetohong tse fetotsweng tsa tshepe, moo e sebetsang e le ligand kapa co-catalyst, e tlatsetsang bokgoning le kgethong ya diphetoho tse fapaneng tsa maiketsetso. Tshebediso ya yona diphetohong tse kopanyang, hydroboration, le ditshebetso tsa ho kenya tshebetsong ha CH e thusa kaho ya ditlamo tsa carbon-carbon le carbon-heteroatom, e tshehetsang ntshetsopele ya dibopeho tse ntjha tsa dikhemikhale le thepa tse nang le ditshebediso tse ka bang teng k'hemistring ya meriana, saense ya thepa, le dipatlisiso tsa agrochemical. Ho feta moo, motsoako ona o sebediswa lefapheng la ho kopanya dimolekhule tsa chiral le tlhahiso ya metsoako e ruisitsweng ke enantioen. Jwalo ka motheo o feto-fetohang ho catalysis e sa lekanang, o nolofalletsa ho thehwa ha dihlahiswa tse hlalositsweng ka stereo tse nang le bohloeki bo phahameng ba optical, e leng ntho ya bohlokwa ho kopanyeng meriana, ditatso le thepa e tswetseng pele. Ho feta moo, Diethyl(3-pyridyl)borane e fumana thuso dipatlisisong tsa thuto le tsa indasteri e le reagent bakeng sa phetoho ya dimolekhule le e le sesebediswa ntshetsopeleng ya mekgwa e metjha ya maiketsetso. Karolo ya yona baelojing ya dikhemikhale, k'hemistri ya meriana le dithuto tsa mechine e tshehetsa kgatelopele ho sibollweng ha dithethefatsi, dipatlisisong tsa baeloji ya dikhemikhale, le kutlwisisong ya ditsamaiso tse rarahaneng tsa baeloji. Ka bokhutšoanyane, ditshebediso tse fapaneng tsa Diethyl(3-pyridyl)borane di totobatsa bohlokwa ba yona ho kganneng boqapi, ho nolofalletsa ho kopanngwa ha dimolekhule tse rarahaneng, le ho thusa kgatelopele mafapheng a fapaneng a dikhemikhale le a saense, e leng se etsang hore e be karolo ya bohlokwa ntshetsopeleng ya thepa e ntjha le metsoako e sebetsang.
