In Total Synsthesis II, starting on page 53, Strike tells us of a recurring dream of ketone synthesis. Questions: 1) The graphic shows the reaction starting with Safrole, the text says start with isosafrol. Which is correct? 2) After addition of the acetone solution, is the ice bath maintained overnight, or is no more ice required after the addition? Is it a matter of keeping the temp at 10 - 20 C overnight or just during the addition / reaction period? The motor in a stir plate could produce enough heat to cause the solution to exceed 20 degrees, but one could (in most areas) construct a flow-through waterbath using tapwater to keep the temp below 20 for extended periods.
