Is e pivalaldehyde (CAS: 630-19-3) an cruth trimethyl de acetaldehyde.Is e aldehyde a th’ ann le buidheann R a tha gu math tomadach, a’ bhuidheann treas ìre-butyl ceangailte ris a’ charbonyl, > C = O.Tha pivalaldehyde na stuth amh cudromach agus eadar-mheadhanach air a chleachdadh ann an synthesis organach, cungaidhean-leigheis, agro-cheimigean agus stuthan dath.Tha pivalaldehyde air a chleachdadh mar thagradh synthesis stereoselective.Tha e cuideachd air a chleachdadh mar bhloc togail a thathas a’ cleachdadh ann an ath-bheachdan dùmhlachd aldol.Mar thoradh air acetaldehyde, faodar trimethyl acetaldehyde a chleachdadh airson acetate a dhèanamh.Faodar a chleachdadh cuideachd mar ro-ruithear airson saothrachadh derivatives pyridine, pentaerythritol, agus crotonaldehyde.
