| titleOfInvention | Method for the preparation of new Isomeric 3,3-diarylphtallides |
| abstract | A method of producing new isomericsn3,3-diarylphthalides of the general formulasn1 and 2, wherein R is halogen, alkyl ornaryl, characterized in that the acid is of the general formulan3, wherein R is as defined above, submitsncondensation with meta-cresol,nat 115-130 ° C, in the presence of chloridenzinc, and the resulting alloy dissolves innglacial acetic acid and poured into water,nthe precipitate formed is filtered off, washed with water,nfollowed by an aqueous solution of sodium carbonate,nthen the resulting mixture of isomers is separatednin a known way. |
