Il est montré que le pérylène peut être formylé par la N‐méthylformanilide en présence d'oxychlorure de phosphore, et que le monoaldéhyde obtenu est le 3‐formylpérylène. Cette réaction constitue une voie d'accès vers de nombreux dérivés monosubstitués du pérylène, et s'applique également au 3‐méthylpérylène.
N-(p-Cyclopentylphenyl)tetrachlorophthalimide. To a boiling solution of 1 g. of tetrachlorophthalic anhydride in 15 ml. of acetic acid, 0.6 g. of p-cyclopentylaniline was added dropwise, and the mixture refluxed for a few minutes. The solid formed after cooling was recrystallized from acetic acid, giving shiny colorless needles, m.p. 242°.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
