Abstract
Dr. Alwyn G. Evans and M. A. Weinberger write : βIn our recent communication on this subject [Nature, March 29, p. 437], it is stated that the addition of acetone vapour, purified by distillation in vacuo over freshly distilled sodium, to a non-reacting mixture of di-isobutenevapour and boron trifluoride initiates the fast reactionof di-isobutene. In our corrected proof of this letter [received too late for changes to be made. Editors] we deleted this statement on the grounds that since traces of water are so effective in initiating this reaction, we do not as yet wish to claim that completely pure acetone itself is effective in this way.β
