Vinyl or p-methoxyphenyldiazomethane reacts rapidly with cephalosporins in ether/methylene chloride cosolvent to give the C-9 allyl and p-methoxybenzyl esters, respectively, in good yields, with no isomerization of the double bond to Δ-2.

Organoaluminum-promoted single homologation of aliphatic and aromatic ketones with diazoalkanes has been described, and among various organoaluminum reagents, especially bulky methylaluminum bis(2,6-di-tert-butyl-4-methylphenoxide) (MAD) is found to be highly effective for the selective homologation of various ketones.
