The thermal decomposition of 1,4-di(heteroallyl)substituted benzenes H2C=CHCH2X-C6H4-XCH2CH=CH2 (X = O, S) in the gaseous phase produces para-benzoquinone, monothio or dithio para-benzoquinone, with 1,5-hexadiene as leaving molecule.The PE spectroscopic evidence can be further substantiated applying the shortway pyrolysis techniques to register also, after isolation in an argon matrix at 10 K, the UV and IR spectra of the short-lived species.Ionisation and electron excitation energies as well as other molecular properties of the violet 2,5-cyclohexadiene-1,4-dithione S=C2C=S correlate satisfactorily with precalculated MNDO values.

A convenient synthesis of aryl alkyl sulphides under solid-liquid phase transfer conditions (using triethylbenzylammonium chloride as catalyst and solid KOH) (TEBA/KOH) from aryl halides and thiolate ions generated in situ from thioiminium salts, is described.
