Addition of Maleic Anhydride to Anethole [PDF]
Nature, 1948 ONE of us1 has earlier obtained a small amount of a crystalline compound (m.p. 241°, decomp.) of anethole with two moles of maleic anhydride, the main bulk of the reaction product being a hetero-polymer1,2,3. We found that, if a small amount of dimethylaniline is added, the formation of the hetero-polymer product is prevented and the yield of the ...
