Description

But-1-en-2-ylbenzene, stabilized with MEHQ, features a reactive vinyl group adjacent to a phenyl moiety, enabling efficient coupling in transition-metal-catalyzed transformations. This bench-stable intermediate exhibits enhanced shelf life under standard conditions and integrates readily into synthetic sequences requiring conjugated alkenylarenes.

Application

But-1-en-2-ylbenzene, 95% (stabilized with MEHQ) serves as a versatile vinylarene building block in transition-metal-catalyzed couplings and electrophilic functionalizations. Its stabilized alkene moiety exhibits enhanced bench stability and compatibility with palladium- and nickel-catalyzed cross-coupling reactions. The compound facilitates efficient access to substituted styrenes and conjugated systems, offering predictable reactivity and straightforward purification under standard laboratory conditions.
