Bentsylideeniasetoni eli bentsaaliasetoni (C10H10O) on aromaattinen α,β-tyydyttymätön ketoni. Yhdistettä käytetään orgaanisessa synteesissä ja hajusteissa.

Ominaisuudet

Huoneenlämpötilassa bentsylideeniasetoni on valkoisia tai kellertäviä kiteitä. Yhdiste liukenee yleisimpiin orgaanisiin liuottimiin, kuten etanoliin, asetoniin, dietyylieetteriin ja bentseeniin, mutta on veteen liukenematonta.[2][4]

Valmistus ja käyttö

Bentsylideeniasetonia valmistetaan emäskatalysoidulla aldolikondensaatiolla bentsaldehydistä ja asetonista.[5][4]

Bentsylideeniasetonia käytetään pääasiassa orgaanisessa synteesissä ja siitä valmistetaan muita yhdisteitä. Esimerkiksi vedyllä pelkistämällä bentsylideeniasetonista muodostuu bentsyyliasetonia.[2][4] Yhdistettä voidaan käyttää myös ligandina organometalliyhdisteissä kuten (η4-bentsylideeni)trikarbonyyliraudassa, jota muodostuu bentsylideeniasetonin ja dirautanonakarbonyylin välisessä reaktiossa ja jota käytetään katalyyttinä orgaanisissa reaktioissa[6]. Bentsylideeniasetonia voidaan käyttää myös fiksatiivina hajustevalmisteissa ja apuaineena päällystettäessä metalleja sähkökemiallisesti.[5][7]
