A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Recommanded Product: N1,N3-Dibenzylpropane-1,3-diamine, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 10239-34-6, Name is N1,N3-Dibenzylpropane-1,3-diamine, molecular formula is C17H22N2. In a Article, authors is Garcias-Morales, Cesar，once mentioned of 10239-34-6
The effect of the nitrogen nonbonding electron pair on the 1JC,H values of 1,3-diazaheterocycles was analyzed and compared to 1,5-diazabiciclo[3.2.1]octanes, which have a restricted conformation. The 1JC,H values were measured by observing the 13C satellites in the 1H NMR spectra and then determining the 1H-coupled 13C NMR spectra. The 1JC,H values are 10 Hz larger when the alpha-hydrogen is synperiplanar rather than antiperiplanar to the nonbonding electron pair on the nitrogen, which serves as experimental evidence of the orbital n N?sigmaC,Hap interactions. In addition, the homoanomeric effect from the interactions of the nitrogen lone pair with the antibonding orbital of the equatorial hydrogen, which was in the beta position, was discussed (nN?sigmaC(beta),H eq).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10239-34-6, help many people in the next few years.Recommanded Product: N1,N3-Dibenzylpropane-1,3-diamine
