What Metals React With Water to Produce Hydrogen? | …
When sodium metal reacts with water, the resulting heat melts the metal almost immediately into a grey-silver ball. The hydrogen gas evolved during this reaction propels the ball rapidly across the surface of the water, leaving a white trail of sodium hydroxide that eventually dissolves into a clear solution.

Wang et al.  used nanocrystals of metal oxides such as TiO 2, Co 3 O 4, Cr 2 O 3, Fe 2 O 3, Mn 2 O 3, NiO, CuO, and ZnO as modifiers in aluminium metal powders to produce hydrogen by a room-temperature reaction with deionised water or tap water.
Hydrochloric acid - Wikipedia
Hydrochloric acid is the simplest chlorine-based acid system containing water. It is a solution of hydrogen chloride and water, and a variety of other chemical species, including hydronium and chloride ions. It is a naturally-occurring component of the gastric acid produced in the digestive systems of most animal species, including humans.

Chemical Reactivity - Michigan State University
Since organometallic reagents function as powerful nucleophiles, selective metal hydrogen exchange, Metalation, would represent a powerful first step to that end. The organometal species produced in this way could then react with a variety of common electrophilic reagents (e.g. alkyl halides, carbonyl compounds and halogens).
