Alkane and alkene dehydrogenation

it may be concluded that conjugated dehydrogenation of isoamylenes similar in isomeric composition to industrial fractions gives a high isoprene yield. Despite relatively 

Conjugated Reactions of Oxidation with Hydrogen Peroxide in the Gas Phase 

The efficiency of conjugated dehydrogenation of olefins with hydrogen peroxide was also confirmed in studies of propylene dehydrogenation to allene [60], The well-known process of propylene oxidative dehydrogenation to allene in the presence of iodine [61] at 625-700 °C gives low yields of the target product (3.6% allene) at low selectivity of the process (6%).
