Hydrogen atom abstraction or hydrogen atom transfer (HAT) in chemistry is any chemical reaction in which a hydrogen free radical is abstracted from a substrate according to the general equation:

X. + H-Y -> X-H + Y.

Examples of HAT reactions are oxidative reactions in general, hydrocarbon combustion and reactions involving cytochrome P450 containing an iron(V)-oxo unit. The abstractor is usually a radical species itself. An example of a closed-shell abstractor is chromyl chloride. HAT can take place through proton-coupled electron transfer.[1] A synthetic example is found in iron zeolites, which stabilize Alpha-Oxygen
