Steric Effects in the Ring-expansion of Coumarins by 2-Diazopropane and t-Butyldiazomethane

3-Cyanocoumarin gives in high yields its 4-isopropyl derivative with 2-diazopropane and its 4-t-butyl derivative with t-butyldiazomethane showing that the 4-alkylation of 3-cyanocoumarin is general and unaffected by bulky substituents on the diazoalkane.W
