Description / Table of Contents:
Diazepine, 27. - Substituenten-Einfluß auf die Bromierung von 2,3-Dihydro-1,4-diazepinium-SalzenDie Bromierung der Ringposition 6 von 2,3-Dihydro-1,4-diazepinium-Salzen 1 sowie der p-Stellung von 6-Phenylresten wird sterisch nicht nur durch Substituenten in vicinalen Ringpositionen sondern auch durch solche in den Stellungen 1, 2 und 4 behindert.
Notes:
Bromination at the 6-position of 2,3-dihydro-1,4-diazepinium salts 1 or at the p-position of a 6-phenyl substituent is subject to steric hindrance, not only by substituents at vicinal sites in the ring(s), but also by substituents at the 1-, 2-, and 4-positions.
