Dearylation of arylphosphine oxides using a sodium hydride-iodide composite

A new protocol for the dearylation of arylphosphine oxides was developed using sodium hydride (NaH) in the presence of lithium iodide (LiI). The transient sodium phosphinite could be functionalized with a range of electrophiles in a one-pot fashion.

Characteristic odoriferous compounds of brown algae: Syntheses of possible oxidation products of (6Z,9Z,12Z,15Z)-1,6,9,12,15-heneicosapentaene and (6Z,9Z,12Z,15Z,18Z)-1,6,9,12,15,18-heneicosahexaene

The unsaturated aldehydes (3Z,6Z)-3,6,11-dodecatrienal (9), (2E,4Z,7Z)-2,4,7,12-tridecatetraenal (10) and (3Z,6Z,9Z)-3,6,9,14-pentadecatetraenal (11) are expected to be products of the air oxidation of heneicosapentaene 1 and heneicosahexaene 2.The first attempts to synthesize aldehydes 9 and 11 (which failed) were based upon repeated Horner-Wittig reactions with phosphine oxide 12.In a second attempt, acetylene chemistry was applied to prepare aldehydes 9, 10 and 11.Their olfactive properties are described.
