✦ Synopsis

The '€I and -C NMR signals of cyclohexyl phenyl sulphides, sulphoxides and sulphones were almost completely assigned, and the effects of diastereotopism in cis-4-tert-butylcyclohexyl phenyl sulphoxide were rationalized. Substituent effects on the "0 chemical sbift of numerous sulphoxides and sulphones are discussed. An unusual paramagnetic y gauche effect on the "S nucleus was detected in cis-4-tert-butylcyclohexyl phenyl sulphone.

Pyridofuroxan ([1,2,5]oxodiazolo [3,4-b]pyridine 1-oxide) undergoes isomerization between the N1oxide and N3-oxide forms which can be observed by the 1 H, 13 C and 15 N NMR spectroscopy but not by 14 N and 17 O NMR at ambient and low temperatures. The rearrangement becomes slower at low temperatures
