Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability. Kawai (Sci. Papers Inst. Phys. Chem. Res.‚ 1925‚ 3‚ 263) has shown that the monoallyl ether of pyrocatechol undergoes the Claisen rearrangement to give an oil

at 59.5 grams before and after the reaction. The theory of conservation of mass states that mass cannot be created or destroyed‚ and this experiment supported that theory. Therefore‚ the combination of liquid lead nitrate and sodium iodide to create solid lead iodide and liquid sodium nitrate did not violate the conservation of mass. Experiment one is in support of the conservation of energy pertaining to chemicals because heat energy was released when magnesium (Mg) and hydrochloric acid (2 HCl)
