Abstract

Abstract 1-Dimethylaminomethyl-naphthol-(2) kondensiert in siedendem Chlorbenzol mit 2- Methyl-dihydroresorcin, 2-Acetamido-dihydroresorcin, Indandion-(1.3), 2-Benzoyl-und 2- Diphenylacetyl-indandion-(1.3) bei Gegenwart katalytischer Mengen von Magnesiumäthylat. Die Kondensation gelingt mit Dihydroresorcin sowie mit dessen 5-Methyl-, 5-Phenyl-und 5.5- Dimethyl-Derivaten hingegen ohne basisches Kondensationsmittel.—Nur bei 2-Methyl- ...
