The present invention is directed to an efficient process for preparing benzoxazole derivatives comprising the step of reacting a 4-Amino-3-hydroxybenzoic acid compound of Formula III with a 3,5-Dichlorophenyl ortho ester compound of Formula II to provide the compound of Formula I wherein R1, R2a, R2b and R2c are as described herein.
Modulating the propeller-like shape of a tripodal C(CH2PPh2)3 fragment by the size of the substituent at the pivotal carbon atom in macrobicyclic tri-λ5-phosphazenes
The chiral macrobicyclic tri-λ5-phosphazenes formed by tripod–tripod coupling of tris(3-azidobenzyl)amines and 1,1,1-tris[(diphenylphosphino)methyl]methanes present helical topologies as a result of combining two propeller-shaped tripodal fragments with the same sense of twist. The introduction of a series of Rpiv substituents of increasing size at the pivotal carbon of the lower tert-butane fragment

The present invention relates to a process for simultaneously consecutive preparation of polyols by base-catalysed reaction of at least two different mid-chain aldehydes with formaldehyde. The simultaneous consecutive mode of operation makes it possible to achieve high conversions and high selectivities for both aldehydes, with additional achievement of a distinct reduction in the amount of unreacted formaldehyde remaining. This leads to improved process economics, since the energy costs for workup of the formaldehyde stream are distinctly reduced.

Um die durch unterschiedliche Wassergehalte des Innenpapiers von beidseitig mit Polyolefin beschichteten Papierunterlagen farbphotographischer Aufzeichnungsmaterialien bedingten Härtungsschwankungen zu vermeiden, wird den Beschichtungslösungen bei der Herstellung des Aufzeichnungsmaterials 1,3,5-Triacrylhexahydro-1,3,5-triazin als Härtungsmittel und ein mehrwertiger aliphatischer Alkohol mit 3 bis 10 Kohlenstoffatomen zugesetzt, wonach die Beschichtungslösungen auf eine coronabestrahlte Oberfläche der Unterlage aufgetragen werden.
