The reactions of π-benzoquinone (BQ) with alkylaluminium compounds of the R3Al (R = Et, i-Bu) and RAlCl2 (R = Me, Et, i-Bu) type have been investigated. It was found that hydroquinone and a respective alkylhydroquinone are formed after hydrolysis, from the reaction of BQ with R3Al; hydroquinone and a respective p-alkoxyphenol are formed from reaction of BQ with RAlCl2 (R = Et, i-Bu). In addition to

acetylenes substituted with alkyl groups and terminal acetylenes substituted with alkyl, aryl, and functionallized alkyl groups are converted to disubstituted quinones by the photochemical reaction with Fe(CO)5 followed by treatment with Ce(IV).
