Abstract
A method of preparing hydroquinone derivatives represented by the formula ** (See formula) ** where Y represents two CH3-O- groups or a monocyclic moiety (see formula) condensed to said hydroquinone entity forming together a naphthalene skeleton, R is a residue of the prenoid chain represented by the formula: ** (See formula) ** where n is 0 (zero) or an integer from 1 to 9 inclusive, and A and B are hydrogen atoms or may optionally form a direct bond between them, which comprises condensing a 2-halo-3- derivative methyl-l, 4-hydroquinone represented by the formula: ** (See formula) ** wherein X is a halogen atom and Y has the same meanings as mentioned above with respect to formula (I) above, with a π -alyl type halogen-nickel complex compound represented by the formula: ** (See formula) ** where the symbols X are halogen atoms, the symbols R have the same meanings as mentioned above with respect to formula (I) above, and each bond with a single dotted line (see graph) represents a semi-link, while each of the links have, combined, the solid line and a dotted line (see graph) represents a semi-double bond.
