Abstract: Reactions of Lithium Phenylacetylenide and Lithium 3,3-Dimethylbut-1-ynide with 3,6-Di-tert-butyl-1,2-benzoquinone. Molecular Structure of 2,5-Di-tert-butyl-8-(3,6-di-tert-butyl-1,2benzoquinon-4-yl) -8-phenylocta-2,4,6,7-tetraen-1,6-olide.-Lithium phenylacetylenide (IIa) and lithium 3,3-dimethylbut-1-ynide (IIb) react in multistage processes with the benzoquinone (I) to the hydroxycyclohexadienones (III), to the allenic compound (IV), or to the bis-decadienynolide (VI), depending on the reaction conditions.
