摘要
In diene-additions of maleic-anhydride with naphthalene derivatives at 8-10000 atm, some derivatives react only under pressure, others react with pressure much better than without Substituents in 1- or 1,4- positions direct the addition to the unsubstituted ring. Alkyl substituents in 2- or 2,3- positions direct the addition to the substituted ring. The proportion of endo-isomer was determined by jodlactonetitration. © 1969.
