The Mass Spectrometry of Some Bis (Trimethylsiloxy)Naphthalenes

Mass spectrometric data were reported for 1,4-; 1,5-; 1,6-; 1,7- and 2,6-bis(trimethylsiloxy)naphthalenes. By the use of metastable-ion measurement the major fragmentation pathways of the five compounds have been deduced. The doubly charged ion and ion-molecule-reaction ion were also discussed.
