The Development of Synthetic Routes to 1,1,n,n-Tetramethyl[n](2,11)teropyrenophanes

A concise synthetic approach to 1,1,n,n-tetramethyl[n](2,11)teropyrenophanes has been developed. It involves the construction of triply-bridged pyrenophanes, during which the three bridges are installed successively using Friedel-Crafts alkylation, Wurtz coupling and McMurry reactions. At the same time, the innate regiochemical preferences of pyrene toward electrophilic aromatic substitution are relied upon to control the substitution pattern. A cyclodehydrogenation reaction is then employed to generate the teropyrene system directly in a nonplanar conformation. The crystal structure of 1,1,7,7-tetramethyl[7](2,11)teropyrenophane was determined and the teropyrene system was found to have an end-to-end bend angle of 177.9°.

Boron trifluoride-mediated alkylation of diphenylphosphine with tert-alkyl fluoride

(Chemical Equation Presented) Treatment of tertiary alkyl fluoride with diphenylphosphine in the presence of a stoichiometric amount of boron trifluoride etherate yields the corresponding tert-alkyldiphenylphosphine despite the coexistence of the strong L

A Convenient Synthesis of Acyclic 1,n-Diketones (n=5-8) from 2-t-Butylperoxycycloalkanones

The reaction of organolithium with 2-alkyl-2-t-butylperoxycycloalkanones, readily available from t-butylperoxylation of 2-alkylcycloalkanones, gave 2-t-butylperoxy-1-cycloalkanol derivatives quantitatively, thermal decomposition of which with or without an acid afforded 1,n-diketones (n=5-8) in excellent yields.
