The present invention relates to an improved process for the preparation of Coenzyme Q. Coenzyme Q10 or CoQ10 has the chemical name 2-[(all-trans)-3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetracontadecaenyl]-5,6-dimethoxy-3-methyl-1,4-benzoquinone and has the formula I. The invention also provides new intermediates useful for the preparation of CoQ10 and processes for their preparation.
