Provided is an aldehyde composition including an aldehyde represented by General Formula (1) below and an aldehyde represented by General Formula (2) below, and a mass ratio between the aldehyde represented by Formula (1) and the aldehyde represented by Formula (2), [(1)/(2)], is from 96/4 to 99.9/0.1:

##STR00001##

where R represents a methyl group or a hydrogen atom.

An aryl-substituted alkanal compound having a molecular weight of less than 300 g/mol and which bears a substituent on the aryl ring ortho to a substituent bearing the aldehyde functionality. Said compounds are useful as perfume ingredients in personal care and household care products.

meta-Substituted 3-phenylpropanal derivatives useful in providing watery-marine, floral-aldehydic notes.

This disclosure is directed to methods of preparing organic aldehydes, each method comprising contacting a terminal olefin with an oxidizing mixture comprising: (a) a dichloro-palladium complex; (b) a copper complex; (c) a source of nitrite;
under aerobic reaction conditions sufficient to convert at least a portion of the terminal olefin to an aldehyde.

SUMMARY

Suggested are cyclopropyl derivative according to formula (I)

##STR00001## wherein R.sup.1 represents a cyclopropyl or C.sub.1-C.sup.6-alkylcyclopropyl residue; R.sup.2 stands for a COR.sup.3 or (CH.sub.2).sub.nR.sup.4 radical; R.sup.3 stands for linear or branched C.sub.1-C.sub.6 alkyl; R.sup.4 stands for CH.sub.2OH or CHO; and n stands for an integer of from 1 to 12. The derivatives are characterized by very intense, but also very different scents, depending on their structure.
