A 'meta effect' in the fragmentation reactions of ionised alkyl phenols and alkyl anisoles

The competition between benzylic cleavage (simple bond fission [SBF]) and retro-ene rearrangement (RER) from ionised ortho, meta and para RC 6H4OH and RC6H4OCH3 (R = n-C3H7, n-C4H9, n-C5H11, n-C7H15, n-C9H19, n-C 15H31) is examined. It is observed that the SBF/RER ratio is significantly influenced by the position of the substituent on the aromatic ring. As a rule, phenols and anisoles substituted by an alkyl group in meta position lead to more abundant methylene-2,4-cyclohexadiene cations (RER fragmentation) than their ortho and para homologues. This 'meta effect' is explained on the basis of energetic and kinetic of the two reaction channels. Quantum chemistry computations have been used to provide estimate of the thermochemistry associated with these two fragmentation routes. G3B3 calculation shows that a hydroxy or a methoxy group in the meta position destabilises the SBF and stabilises the RER product ions. Modelling of the SBF/RER intensities ratio has been performed assuming two single reaction rates for both fragmentation processes and computing them within the statistical RRKM formalism in the case of ortho, meta and para butyl phenols. It is clearly demonstrated that, combining thermochemistry and kinetics, the inequality (SBF/RER) metaorthopara holds for the butyl phenols series. It is expected that the 'meta effect' described in this study enables unequivocal identification of meta isomers from ortho and para isomers not only of alkyl phenols and alkyl anisoles but also in other alkyl benzene series.

Alkylphenol synthesis using heteropoly acid catalysts

Disclosed is a one step method for synthesis of alkylphenols which comprises reacting phenol with the corresponding olefin under adiabatic conditions in the presence of a catalyst comprising a heteropoly acid represented by the structure: where x=P or Si, M=Mo or wv and n is an integer which is 4 or 5, alone, or deposited on an inert support, at a temperature of from 60° C. to 250° C. and a pressure of from near atmospheric to about 500 psi.

Preparation of nonionic surfactants by oxyalkylation with a phenolic activated magnesium catalyst

Nonionic surfactants containing a narrow molecular weight distribution is obtained by the use of a magnesium-containing catalyst which comprises reacting a reactive hydrogen compound selected from the group consisting of monohydric alcohols having from about 6 to 30 carbon atoms with an alkylene oxide having from 2-4 carbon atoms at a temperature at which the reaction proceeds in the presence of at least a catalytic amount of a phenolic activated magnesium catalyst containing phosphorus.
