	Ethynylbenzaldehyde 4-Ethynylbenzaldehyde, or ''p''-ethynylbenzaldehyde, is an organic compound with the formula HC2C6H4COH. It is an ethynyl derivative of benzaldehyde, or may also be viewed as a formylated derivative of phenylacetylene. Preparation 4-Ethynylbenzaldehyde may be prepared by the Sonogashira coupling of 4-bromobenzaldehyde with trimethylsilylacetylene to form 4-((trimethylsilyl)ethynyl)benzaldehyde, followed by removal of the trimethylsilyl group with base to form 4-ethynylbenzaldehyde. Reactions The ethynyl functionality of 4-ethynylbenzaldehyde may undergo a Sonogashira coupling with another molecule of 4-bromobenzaldehyde to form the symmetrical dialdehyde In organic chemistry, an aldehyde () is an organic compound containing a functional group with the structure . The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group ... 4,4'-(ethyne-1,2-diyl)dibenzaldehyde.
