WebMyth: Lithium-ion fires are typical of other industrial fires, and don’t need specific emergency response planning. Reality: These fires have unique attributes and are very difficult to extinguish. In fact, you may need to let the fire burn out. That’s due to additional cells rupturing due to fire and heat, releasing flammable vapor. Webmethyl 4'-bromo-biphenyl-4-carboxylate 0.54 g (2.5 mmol) of methyl 4-bromo-benzoate is dissolved in 10 mL dioxane and 2.5 mL 2M-sodium carbonate solution. 0.6 g (3 mmol) of 4-bromophenyl-boric acid and 0.12 g (0.1 mmol) of tetrakis-(triphenylphosphine)-palladium are added successively and the reaction is refluxed for 5 hours.
