摘要：

A range of diazocarbonyl compounds 1-9 containing two different functional groups has been prepared, and their rhodium(II) catalysed decomposition studied as a means of probing the chemoselectivity of carbenoid intermediates. The results indicate that whereas O-H insertion reactions predominate over cyclopropanation and aromatic insertion reactions, carbonyl ylide formation vs. other competing processes is more finely balanced, and is catalyst dependent.
