Iii. 2-Methoxy-4',5-Bis(carboxymethyl)diphenyl Ether

Abstract

Benzoylation by the Schotten-Baumann procedure converted the diamine to an amorphous dibenzoyl derivative which was apparently associated with two molecules of benzene.

Studies on Bis-(benzylisoquinolines). I. Synthesis of dl-N-(4-Hydroxyphenylacetyl)-5-iodo-4-acetoxy-3-methoxyphenylalanine Methyl Ester

“…Previous methods for the preparation of triarylalkoxysilanes and triarylaryloxysilanes have been reviewed recently,2 as have methods for the preparation of unsymmetrical disiloxanes. 3 The most convenient and versatile of the previous methods for the synthesis of either of these types of compounds has been the reaction between a triarylchlorosilane and a metal salt of an alcohol, phenol or silanol. Of the compounds listed in Table I only triphenylethoxysilane,2•4 hexaphenyldisiloxane3•5 and 1,1, l-triphenyl-3,3,3-tri-/>-tolyldisiloxane3 have been prepared previously.…”
