A mass spectrometric study of the trimethylsilyl derivatives of a group of amino‐hydroxy, dihydroxy and dicarboxydiphenyls has disclosed that these compounds produce a number of intense doubly‐charged ions ([M – 30]/2, 5 to 27%), for which the singly‐charged ions are low or absent. The derivative of 4,4′‐dicarboxydiphenyl yields five such doubly‐charged ions with relative intensities ⪖ 3%. The fragmentation pathways for this compound have been studied by the formation and mass spectrometry of the trimethylsilyl‐d9 derivative.
