Promotion of selectivity through organised media: Fries rearrangement of calix (n) arene esters (n = 4,6,8)
Chawla, H. Mohindra,Meena

Fries migration of various calix(n)arene esters (n = 4,6,8) under the influence of different solvents (benzene, nitrobenzene, chlorobenzene, carbon disulphide, toluene, xylene, mesitylene) and Lewis acid catalysts (aluminium chloride, ferric chloride and boron trifluoride etherate) has been examined. It appears that the best conditions for the conversion of calix(n)arene esters to p-acyl calix(n)arenes involve the use of aluminium chloride as the Lewis acid and carbon disulphide or benzene as solvent. The use. of toluene or mesitylene as a solvent leads to regioselective formation of their acyl derivatives probably through the intermediacy of a host guest complex of the solvent with calix(n)arenes.

The para-acylation of calixarene (2), calixarene (3), and calixarene (4) by Friedel-Crafts reaction with a wide variety of acyl chlorides leads to 5-7 in moderate to good yields.Friedel-Crafts reaction of 26,28-dimethoxycalixarene (8) gave products 9 selectively disubstituted in the para-positions of phenol rings. - Key Words: Calixarenes / Friedel-Crafts reaction, selective

The base-induced condensation of p-phenylphenol and formaldehyde is shown to yield p-phenylcalixarene 3 and p-phenylcalixarene 5 as isolable products but no detectable amount of p-phenylcalixarene 1, contrary to earlier reports.As an alternative
