Daim ntawv thov
① Tubtxib Tes Haujlwm 2-(Di-tert-butylphosphino)biphenyl ua lub siab-kev ua tau zoo phosphine ligand rau Pd- catalyzed coupling cov tshuaj tiv thaiv (Suzuki, Stille, Buchwald-Hartwig nyob rau hauv C/7} daim ntawv cog lus), accele intermediate synthesis.
② Pab 2-(Di-tert-butylphosphino)biphenyl CAS 224311-51-7 ua cov ligand tseem ceeb rau Ni/Cu-catalyzed cov tshuaj tiv thaiv, pab txhawb kev ua haujlwm catalytic rau sterically hindered aryl halide substrates.
③ Kev ua haujlwm ua ntej rau kev hloov pauv hlau complexes, optimizing catalytic systems thiab txhim kho cov tshuaj tiv thaiv tawm los thiab kev xaiv hauv organic synthesis.
Cia thiab ceev faj
Khaws 2-(Di-tert-butylphosphino)biphenyl CAS 224311-51-7 ntawm 0-25℃hauv N₂/Ar-sealed amber iav/HDPE ntim rau hauv ib qho chaw txias, qhuav, tsaus thiab tsis muaj oxygen noo noo, ncaj qha tshav ntuj thiab oxidants. Hnav hnab looj tes nitrile, looj tsom iav dub thiab plua plav npog; tsis txhob nqus pa, daim tawv nqaij / qhov muag sib cuag thiab noj, raws li nws muaj kev phom sij yog tias nqos thiab khaus rau cov mucous daim nyias nyias. Reseal nruj nreem tom qab siv los tiv thaiv oxidation. Pov tseg los ntawm cov ntawv tso cai pov tseg pov tseg; thauj raws li cov khoom tsis muaj teeb meem, tsis muaj qhov tshwj xeeb inhibitor xav tau.
