“…No isomerisation of the reaction product was also observed in the reaction of 2,2,5,7-tetrafluoroadamantane with BBr 3 . 86 1-Hydroxyadamantane (4) or its nitrate 12 are widely used as starting compounds in the synthesis of halogenoadamantanes. Thus 1-fluoroadamantane (33) was obtained by the reaction of 1hydroxyadamantane (4) with boron trifluoride diethyl etherate.…”
