Phenylacetic aldehyde

Phenylacetic aldehyde, CgHgO, is one of the most important of modern synthetic perfumes. It has not been found naturally in essential oUs. It possesses a powerful odour of hyacinths, and is extremely useful for the reproduction of all odours of this and the narcissus type. 

Phenylacetic aldehyde can be prepared by various methods, of which the following are the principal —...

A detailed study of this dehydrogenative condensation in the presence of triphenylmethyl perchlorate or fluoroborate was made by Simalty-Siemiatycki and Fugnitto. The reaction is best carried out in refluxing acetic acid nitromethane or acetonitrile give less satisfactory results. Chalcone reacts in these conditions with phenylacet-aldehyde yielding 2,4-diphenylpyrylium with an unsubstituted a-position. This and similar 2-unsubstituted pyrylium salts prepared by this method are so reactive that they do not afford pyridines on treatment with ammonia in the usual conditions this behavior is similar to that of the unsubstituted pyrylium perchlorate. The reaction of...
