A variety of polycycles can be synthesized via an intramolecular alkylation cyclization promoted by Ni(PPh3)4 and NaHMDS. Mechanistic investigations support the catalytic nature of Ni0 in the course of TEMPO scavenging experiments and its association with the substrate and NaHMDS to form an adduct by DOSY NMR.
Studies in the Cycloheptane Series. Part - XXXI: Friedel-Crafts Reaction of the Anhydride of αα-Dimethylglutaric Acid with Different Aromatic Hydrocarbons and Synthesis of 1,1-Dimethyl-3,4-benzo/substituted benzocycloheptanes and 1,1-Dimethylthienocycloheptane

The anhydride of αα-dimethylglutaric acid on condensation with benzene, toluene, isomeric xylenes, chlorobenzene, anisole, tetralin, naphthalene and thiophene under F.C. conditions gives the respective αα-dimethyl-γ-aroyl-n-butyric acids which on Clemmensen reduction yield δ-aryl-n-valeric acids.These on cyclisation with PPA furnish III and IV (X=O) which on Clemmensen reduction give the respective hydrocarbons (III and IV: X=H2).
