Convenient syntheses of 1-chloro-, 1-bromo-, and l-iodobicyclo [2.2. 2] octanes are described. Reaction of l-methoxybicyclo [2.2. 2] octanes with acetyl halides in the presence of stannic chloride afforded l-halobicyclo-[2.2. 2] octanes in moderate yields. An analogous reaction of 4-methoxybicyclo [2.2. 2] octan-2-ones with acetyl chloride afforded a mixture of 4- acetoxybicyclo [2.2. 2] octan-2-ones and 4-chlorobicyclo [2.2. 2] octan-2-ones. An acid- ...
