Aryldiazomethanes are converted by rhodium(II) acetate and iodorhodium(III) tetraphenylporphyrin to cis- rather than trans-1,2-diarylethylenes. Secondary aryldiazoalkanes react with rhodirum(II) acetate to give azines.

CDexcitonchiralitymethods are described for the stereochemical assignment of organic compounds containing carboxylic acid groups. Using the chromophoric combination 2-naphthoate or 2-anthroate and 9-anthrylmethyl group the absolute stereochemistry of α- and β-hydroxy carboxylic acids can be deduced from a single CD measurement. Furthermore, as demonstrated with cyclic and acylic dicarboxylic acids

Chiral pool approach using d-glucose, l-xylose, and d- and l-arabinoses was used to obtain four stereoisomeric 3-hydroxy-2-methylbutanoic acids with well defined configurations. The acids were isolated as fluorescent 2-naphthylmethyl esters after reaction with 2-naphthyldiazomethane.
