By CL ARCUS and J. KENYON. p-Toluenesulphinic acid and its esters condense with acetone to produce p-idyl-p-(B-methyZPentan-6-onyZ) suZPhone (I) and evidence supporting this formulation of the condensation product is given. Further evidence is adduced that the condensation proceeds, not by an exchange of carbonium kations, but probably by a rearrangement of diacetonyl P-toluenesulphinate which results from ...
