CAS 2430-99-1: 2-(4-methylphenyl)-1-phenylethanone

4-Methylbenzyl phenyl ketone is a diazo compound with the chemical formula of CHC(O)CH=CCl. It is an organic compound that belongs to the class of stilbenes and is used in chemistry as a reactive intermediate in organic synthesis. 4-Methylbenzyl phenyl ketone can be prepared by the reaction of benzaldehyde and acetophenone with sodium nitrite, which generates a carbene species. The carbene reacts with itself to form the product and releases hydrogen chloride gas. This reaction has been shown to produce yields of up to 85%. 4-Methylbenzyl phenyl ketone reacts with enolates or enolizable compounds to form a diazo group, which can be oxidized using chloroformate esters such as oxypalladation or transition metal complexes such as palladium chloride. This product is stable in air, water, and most organic solvents.
