1.3-Migration Tendency of Silyl Groups in SilyltriazenesSilyl groups in silyl-1.3-dimethyltriazenes MeN = N-NMe(SiR3) migrate between positions 1 and 3 of the triazene chain. From the rate of the 1.3-migration of the silyl groups, measured by 1H n.m.r. spectroscopy, it follows that the migration tendency of the silyl groups SiR3 increases in the following order of the ligands bound to silicon: R = Et 〈 Me 〈 OMe 〈 Cl.
Notes:
Silygruppen in Silyl-1.3-dimethyl-triazenen MeN = N-NMe(SiR3) fluktuieren zwischen den Positionen 1 und 3 der Triazenkette. Aus der Geschwindigkeit der 1.3-Silylgruppenwanderung, die sich 1H-NMR-spektroskopisch bestimmen läßt, folgt zunehmende Wandertendenz der Silylgruppen SiR3 in der Reihenfolge der Liganden R = Ät 〈 Me 〈 OMe 〈 Cl.
