Cov Ntawv Thov
N, n, n, n, n {- tetramethyl ------ Nws lub tsev kawm ntawv qib Tetra-hloov mus raws li kev ua si chiral, pab txhawb kev sib xyaw ua ke. Hauv kev kho tshuaj chemistry, nws tau ua haujlwm hauv kev npaj cov neeg sib tw ntawm cov neeg sib tw ntawm cov neeg sib tw, tshwj xeeb yog qhov tseem ceeb rau kev ua. Ib qho ntxiv, nws tuaj yeem siv rau hauv kev tsim cov tshuaj tiv thaiv tshwj xeeb, catalysts, thiab lub tsev thaiv kev rau cov nyom.
Cov txiaj ntsig
The benefits of N,N,N,N-tetramethyl-L-tartramide come from its stereochemically defined, multifunctional structure and high chemical stability. Nws l {{4 4}} Tartramide Caj qaum caj qaum, uas yog qhov tseem ceeb rau kev tswj hwm enantioselectivity hauv tshuaj lom neeg cov tshuaj tiv thaiv, ua rau nws muaj nuj nqis hauv Asymmetric synthesis. Lub Tetramethyl pab pawg txhim kho solubility thiab txo cov hydrogen {}} kev sib cuam tshuam thiab kev coj ua thiab tshuaj tiv thaiv kev ua haujlwm. Nws cov kev ruaj ntseg nyob rau hauv cov qauv kev kuaj mob thiab sib xyaw nrog ntau yam kev tawm tsam rau ob qho kev lag luam, txhawb nqa tus nqi siab chiral lwg met chirules.
