The use of biomass, in particular for specialty or fine chemicals, requires selective methods of defunctionalization. Current deoxygenation methods often lead to a significant C-C bond breakage of the raw materials. While it is also possible to utilize complex product mixtures in the production of bulk chemicals, a mild, stepwise deoxygenation with high selectivity appears advantageous for the production of specialty and fine chemicals. As a reaction class with great potential, the deoxydehydration (DODH) has been found in recent years, in which olefins can be prepared stereoselectively from diols. The key challenge in furthering the importance of the reaction is to develop cost-effective active, selective and stable catalysts that can ultimately be used in a technical process. Therefore, research is needed to develop suitable molybdenum catalysts instead of the expensive rhenium, and to allow them to react on solid catalysts instead of molecular compounds. All in all, promising transformations to novel compounds will become accessible.

生物质的使用，特别是用于特种或精细化学品，需要选择性的去功能化方法。目前的脱氧方法通常导致原料的显著C-C键断裂。虽然也可以在散装化学品的生产中利用复杂的产物混合物，但具有高选择性的温和逐步脱氧似乎有利于生产特种和精细化学品。脱氧脱水（DODH）反应是近年来发现的一类具有很大潜力的反应，它可以立体选择性地从二元醇制备烯烃。进一步提高反应重要性的关键挑战是开发具有成本效益的活性、选择性和稳定的催化剂，这些催化剂最终可用于技术过程。因此，需要研究开发合适的钼催化剂来代替昂贵的催化剂，并允许它们在固体催化剂上而不是分子化合物上反应。总而言之，有希望的新化合物转化将变得容易。
