~-Phenyl-p-xylyene (7) has been shown to be an intermediate in the base-catalysed decomposition of both p-benzylbenzyltrimethylammonium bromide (11) and p-methylbenzhydryltrimethylammonium bromide (12). All the possible cyclic trimers of unsymmetrical linking are formed (i.e. phenyl-substituted head h to h and tail to tail links), which accompany a polymer formed mainly via the contrasting head to tail linking of ct-phenyl-p-xylylene.
