TRANSACETALISATION DE TRIOLS A PARTIR DU DIMETHOXYMETHANE. SELECTIVITE ET APPLICATIONS SYNTHETIQUES
THe LiBr assisted/acid catalyzed transacetalation of triols from DMM affords a highly selective method for the synthesis of hydroxy compounds bearing a dioxane ring.These compounds might further conveniently be alkylated by phase transfer catalyzis.

Derivatives of Pentaerythritol, I. - Formaldehyde Bis(pentaerythrityl) Acetal and Tetrapentaerythritol
Pure formaldehyde bis(pentaerythrityl) acetal (9) and tetrapentaerythritol (4) were isolated for the first time as by-products during the synthesis of pentaerythritol from acetaldehyde and formaldehyde.The spectra show that 4 is not a branched molecule as suggested but a straight-chained one.
