Abstract

Abstract Various diarylboron chelates of the cyclic B, N-betaine type (2, 7, 11) are synthesized from N-(2-hydroxyalkyl)-N, N-dialkylamine-N-oxides (1) and diarylboron reagents. They are rearranged in a thermally induced intramolecular redox reaction, during which the N-oxide is deoxygenated and the borinic acid moiety is oxidized to the state of boronic acid. The rearrangement products 3, 8 and 12 are converted to new B, N-betaine ...
