摘要

The a-dicarbonyl compounds 1 are selectively reduced to semidione radicals 2 by aqueous Ti", via inner-sphere electron transfer (ET). When an equimolar amount of an arenediazonium salt (3) is present, 2 adds to the nitrogen-nitrogen triple bond of 3 to afford the intermediate am radical cation C, which, depending on the nature of the para substituent of the N-phenyl ring, undergoes rearrangement to al, l-diacyl-2-arylhydrazine (4) or ...
