Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 2213-43-6, molcular formula is C5H12N2, introducing its new discovery. Formula: C5H12N2
Restricted rotation about the N-N bond in unhindered, non-conjugated hydrazones (e.g.Me2N-N=CH2) has been detected by 13C n.m.r. below -150 degC.The results indicate that the N=C plane is coplanar with the dynamically averaged plane of the sp3 nitrogen, in contrast with hindered hydrazones (containing the 2,2,6,6-tetramethylpipridinyl ring, TMP) where the N=C moiety adopts a perpendicular conformation.Effects due to the slowing of ring reversal were not observed in hydrazones containing the TMP ring, but were detected in other hindered derivatives such as TMP-NH2 and TMP-NO.A most interesting feature becomes apparent in two hydrazones with the 2,6-cis-dimethylpiperidinyl (DMP) ring, DMP-N=CH2 and DMP-N=CHPh.In the same molecule the N=C moiety is coplanar with the averaged sp3 nitrogen plane when the methyls are axial, but perpendicular when the methyls are equatorial.
