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.

The aldehyde-selective oxidation of alkenes bearing diverse oxygen groups in the allylic and homoallylic position was accomplished with a nitrite-modifiedWackeroxidation. Readily available oxygenated alkenes were oxidized in up to 88% aldehyde yield and as high as 97% aldehyde selectivity. The aldehyde-selective oxidation enabled the rapid, enantioselective synthesis of an important pharmaceutical
