N-Alkyl- and N-benzyl-4-p-chlorophenyl-2,3,5,6-tetraphenyl- N-alkyl- and N-benzyl-2,3,4,5,6-pentaphenyl-, and N-alkyl- and N-benzyl-2,4,6-triphenyl-pyridinium bromides on pyrolysis at 180-220 deg C give the corresponding alkyl and benzyl bromides in high yield. 1-Benzyl-5,6-dihydro-2,4-diphenylbenzoquinolinium trifluoromethanesulphonate gave benzyl bromide on heating with KBr in dimethylformamide at 100 deg C, and n-octyl bromide (80percent) was obtained from the corresponding pentacyclic bromide in refluxing acetonitrile.
