An unprecedented rhodium-catalyzed selective cleavage of double alkyl-oxygen bonds of bis/tris(o-alkyloxyphenyl)phosphine has been realized, in which P atom functions as a directing group and simple aryl acids are the methyl group acceptor to provide methyl esters and a quaternary phosphonium salt. The preliminary mechanism was investigated via an 18O labeling experiment and stoichiometric reaction between a Rh-A crystal and an aromatic acid.

The interaction of tetrachlorophthalic anhydride with dimethylformamide at its reflux temperature either in the presence or absence of an aryl oxide or alkoxide furnishes predominently N,N-dimethyl-2,3,4,5-tetrachlorobenzamide (3) in contrast to the corresponding acid (4), as reported in literature.
