dibenzylbutane

Dibenzylbutane is an organic hydrocarbon with the formula C18H22. It consists of a four-carbon butane backbone bearing two benzyl substituents, each substituent being a -CH2-Ph group. The molecule can exist as several constitutional isomers depending on the positions of the benzyl groups on the butane chain.

Physical and chemical properties are typical of aromatic benzylic hydrocarbons: it is largely nonpolar and hydrophobic, with limited water solubility and greater solubility in organic solvents such as hexane or toluene. Exact melting and boiling points depend on the isomeric form and on the level of purity. The presence of two benzyl groups makes the compound relatively bulky and can influence its conformational behavior.

In terms of reactivity, the benzylic CH2 groups are the most activated sites, allowing certain benzylic transformations under appropriate conditions. The aromatic rings also contribute to potential electrophilic or radical reactions on the benzyl rings, again depending on the reaction conditions and substituents.

Production and applications are mainly within the realm of organic synthesis and academic research. Dibenzylbutane is not a common industrial feedstock but can appear as an intermediate or reference compound in studies involving benzylic chemistry, hydrocarbon coupling, or the exploration of steric effects in butane derivatives.

Safety considerations are similar to those for other moderate‑sized hydrocarbons: dibenzylbutane is typically flammable and should be handled with standard laboratory precautions, including adequate ventilation and avoidance of inhalation or skin contact.
