                                    Addition of bromine to hydrocarbon 1 results in an aromatic alkylation to form the bicyclo[3.3.1]nonane derivative 5.  Addition of bromine to ketone 3 in acetonitrile solution results in a dienone-phenol rearrangement to form phenol 6, while reaction of ketone 4 with phosphorus pentabromide yields phenols 10 and 11.  This reaction results from a novel ''bromo ketone-phenol'' rearrangement, as demonstrated by the fact that bromo ketones 12 and 13 spontaneously isomerize to 10 and 11.
