反応手順

109 g of CuCl were added in small portions to a Grignard solution prepared from 26.4 g of magnesium turnings and 156.2 g of methyliodide in 200 ml diethylether under a nitrogen atmosphere. To the reaction mixture there were then added 124 g of 4,4-dimethyl-cyclohex-2-en-1-one in ether solution and the whole was refluxed for 2 h. The mixture was then hydrolysed with a saturated aqueous solution of ammonium chloride and subjected to the usual treatments to afford on distillation 88 g (63% yield) of 3,4,4-trimethyl-cyclohexanone;
