Which reaction intermediate is formed when 4-methylcyclohexene reacts with br2 dissolved in ccl4?

The answer is obviously a derivative of calcium borate, which has been used in the aviation industry since the Wright brothers first flew out of Kitty Hawk North Carolina. When the calcium orate interacts with the oxygen in room air, it combusts with the force of 3000 unicorn farts and ignites a flame bigger than that of Michael Jackson and the children at Neverland Ranch.
