The Beckmann rearrangement is a pivotal transformation in organic synthesis, enabling the conversion of ketoximes to amides via a nitrogen migration process. Over recent decades, advancements in ...
Mesoporous crystals are important materials for catalysis and separation. As with so much of chemistry, controlling their properties relies on understanding and then tailoring their structures. This ...
I HAVE recently received my copy of Chemical Reviews for December 1944 and find in it yet one more survey of the Beckmann rearrangement and confession of failure to 'explain the mechanism' in the ...
HIGMAN 1 recently suggested a new mechanism for the Beckmann rearrangement which postulates that the cation (I) rearranges by rotation of the central > C = N < unit through 90° to form (II). This ...
THE recent resurgence of interest in the mechanism of the Beckmann change reflects the perennial fascination which this subject has for chemists. First, Higman 1 and LeFevre 2 have suggested that the ...
