There is disclosed a surprising reaction of an alkane thiol with a catalyst and heat to become dehydrogenated and form a thiophene rather than an expected desulfurization reaction to form the corresponding alkane or alkene. Moreover, there are disclosed surprising results regarding the form of a catalyst to allow a reaction of an alkane thiol to form the dehydrogenated thiophene at lower temperatures and at higher conversion percentages to allow for more efficient recovery of thiophenes to allow for recycling and reuse of thiophenes to hydrogenate to form alkane thiols. Further still, there is disclosed a set of reaction conditions and catalyst presentation that allows for recovery of usable diatomic hydrogen gas from a dehydrogenation reaction of substituted or unsubstituted cyclic thioethers to substituted or unsubstituted thiophene.
